Buying a car ranks right up there with the biggest financial decisions most Kiwis will ever make. It's often a vehicle that can get the kids to school, haul your gear to the beach, as well as battle the daily commute. When you're dropping fifteen grand on wheels, you want something that can actually go the distance.

Everyone's got that friend with the "old faithful" that just refuses to die. Or conversely, a family car nightmare that practically lived at the mechanic's. While flashy features tend to look great on the lot, reliability can sometimes take a back seat, even though that's what actually matters when you're turning the key on a freezing morning. This guide cuts through the noise for buyers chasing a dependable vehicle under $15,000 that won't let them down.

Looks can be deceiving!

Car reliability is much more than just asking "Does it break down or not?"

Real reliability is about a car performing consistently over longer periods. In fact, three things often determine whether a car is truly reliable:

Whether maintenance costs are predictable

But here's what the seller won't tell you. When you're buying second-hand, the factory build quality matters less than you think.

What matters more is how the previous owners treated it. Did they 

? Has it been pranged? A low-k car that's been thrashed and neglected will bite you harder than a high-k vehicle with receipts for every 

The problem is, you can't spot most reliability issues during a quick test drive around the block. Engine wear from skipped oil changes is hidden inside the engine, and any dodgy accident repairs could be covered up without a trace. Electrical gremlins also tend to stay hidden until well after you've signed the papers.

Get a carVertical history report to learn about the car's past

More Kiwi buyers are checking vehicle history before they hand over cash these days. It’s a smart move because a 

 digs up information you'd never know otherwise.

The big one to watch out for is mileage fraud, as it is growing at an alarming rate everywhere. Dodgy sellers wind back odometers to make cars look fresher than they are, meaning up to 25% price inflation on a car that's actually got way more k's, and way more wear, than the dash suggests.

 worldwide to spot these dodgy odometer readings. But that's just the start. You'll also see:

 – what actually happened and how bad it was

 – make sure it isn’t wanted as stolen

 – when it was last checked and registered

Getting a report takes minutes. Simply find the 

 (that 17-character number on the driver's side dashboard or door pillar), enter it into the carVertical website, and you'll get an instant report containing everything you need to know before you commit.

Having a budget doesn't mean you have to compromise everything. The NZ market is full of solid second-hand cars that are fully capable within that bracket. These five cars have proven themselves time and again, as they're the ones that keep running long after their flashier competitors have given up the ghost:

Walk around any New Zealand suburb and count the RAV4s. There's a reason they're everywhere from Auckland to Invercargill – they just don't die!

The engines are bulletproof, parts are cheap and available everywhere, and any mechanic in the country can fix them relatively easily. Fifteen thousand dollars can get you a solid fourth-gen model (2013-2018) with plenty of life left in it.

Both families and active types love them, as they handle the supermarket run and the gravel roads to your mate's place equally well. There’s space for gear, comfort for long trips, but it’s practical enough for daily use.

When searching, watch out for CV joints on higher-k examples, though. Listen for clicking or popping during tight turns during the test drive. And make sure that the auto box shifts smoothly, as some of the older ones can get a bit hesitant if they haven't been looked after.

If you’re looking for a first car, live in the city, or want something economical at the pump, the Mazda Demio (or Mazda2 if you prefer) is another great contender.

It's small enough to park in smaller spots, sips fuel, and Japanese engineering means it'll keep running for ages. Under $15,000 gets you plenty of choice, and there are heaps of these on the market, many with surprisingly low mileage for their age.

They’re cheap to maintain, with parts available and an accessible engine for mechanics. It could be a perfect runabout that won't cost you much to keep on the road. The interior's compact, but it's smarter than you'd think.

Pre-2014 autos can be a bit problematic with their transmissions, though, so test drive carefully and make sure the gears change smoothly. Apart from that, it’s one of the most reliable hatchbacks in NZ and is brilliant value.

An Aqua’s biggest advantage is its incredible mileage capability. This hybrid consistently does under 4L/100km in real driving, not just on paper, so for people racking up city kilometres, it's very cheap to run.

It also exhibits pure Toyota reliability, too. The Aqua thrives on stop-start city traffic, as the hybrid system is designed precisely for that kind of driving. Maintenance is straightforward, and there are no major mechanical dramas to worry about.

However, Aquas do tend to get stolen a lot, and insurance companies are catching on, so your premiums might cost more than you'd like. The hybrid battery will eventually need replacing, too, at $2,000-$4,000 for genuine parts, less for reconditioned.

This is where the non-hybrid Yaris makes sense for some people. It has the same Toyota reliability, stays simple to maintain, but with no battery replacement hanging over your wallet. It is a bit less fuel-efficient, but it avoids those hybrid-specific costs. Both are excellent options.

Perfect for the Kiwi lifestyle. With AWD and decent ground clearance, these are comfortable for long trips. Whether running from city streets to gravel roads to ski field runs, the Outback handles varied conditions brilliantly.

Older Subarus have had a mixed reputation in the past, but the petrol Outbacks from late 2000s/early 2010s remain solid performers if they've been maintained. The combination of station wagon practicality meeting light 

 capability makes them attractive for both families and outdoor types.

Skip the diesel versions from this era, however, as they've proven genuinely problematic. Modern diesels need that DPF (Diesel Particulate Filter) to work properly, and it only regenerates during proper highway driving. As a result, shorter urban trips cause the DPF to clog, leading to poor performance and a hefty replacement bill.

Petrol engines are simpler and way more reliable for normal use. Check the service history carefully, though, and watch for head gasket issues on older models, as they are a known weak spot that was fixed later.

This is an RAV4 alternative that's just as good, and some might even say better! Honda's reliable reputation speaks for itself across many of its cars, and the CR-V is a great example. All the engines can go the distance if you service them properly.

The CR-V is genuinely roomy inside, and its ride comfort is highly rated, making it a family-friendly ride that works well even on long trips. Third-generation models (2007-2011) are all over the market at under $15,000. Running costs are reasonable and maintenance is straightforward, making them brilliant value.

Check the air-con carefully, though, as compressors can fail and they're not cheap to replace. Also listen for suspension noises over bumps. Worn bushes aren't a dealbreaker, but you'll want to know about them before you buy so you can negotiate the price.

If you value space and comfort over everything else, the CR-V won't disappoint and could serve you well for years.

Things that hurt a car's reliability the most

Even bulletproof cars can quickly become money pits if they're mistreated. When you're buying used, knowing what wrecks a vehicle is just as important as picking the right model. Four things kill reliability faster than anything else.

If you skip servicing, problems can quickly escalate. The manufacturer's service schedule is designed to keep the car from destroying itself.

For example, old oil doesn’t protect the engine well. As friction increases, heat builds up, and metal wears down. What starts as "saving money" on an oil change can easily end up as thousands in engine damage or a complete engine rebuild.

The same applies to all of the other fluids in the engine. For example, as brake fluid absorbs moisture over time, your brakes become less effective and even potentially dangerous. Coolant also breaks down, meaning corrosion can eat into your cooling system, radiator, or lead to water pump failure. If the transmission fluid is never changed, this can cause slipping gears and, in the worst case, require a complete replacement.

As such, a car with a full service history is worth a lot more than one without, because you know it's been looked after properly. Check out 

 isn't cosmetic. It's structural damage that eats your car from the inside out. This is especially relevant in NZ, where salty coastal air accelerates the whole process, and not just on older cars!

While surface rust on panels can be ugly, it’s manageable. Structural corrosion on the chassis or suspension mounts, however, can be much more dangerous. Your car can fail its WOF, and in a serious accident, the compromised structure could mean the difference between walking away and not.

Rust causes water leaks, electrical issues, and progressive structural damage. The more it spreads, the more expensive it gets to fix properly. Eventually, extensive rust makes a car economically dead, as the costs to repair can become than its worth.

Get underneath the car and check if you can. Examine the chassis, floor pans, suspension mounts. Surface rust is fine, but if you see bubbling paint or structural rust, walk away.

"I saved heaps on parts!" isn't the advantage some sellers believe it to be. Cheap parts are cheap for a reason: they don't last, and they can wreck other components as they fail.

As an example, imagine a dodgy suspension part that's slightly the wrong size. As a result, your steering and alignment drift, your tyres wear unevenly and need replacing earlier. Other suspension components take extra strain and fail prematurely. What looked like savings on one part costs a lot more further down the track.

It’s the same story for the rest of the parts in your car, too. Cheap brake pads damage rotors, and rubbish oil filters let contaminants into your engine. Bargain-basement timing belts can snap and completely destroy your engine. Although quality parts or genuine OEM might cost more upfront, their extensive QA means they last longer and protect everything around them.

When you're looking at a used car and the seller brags about cheap parts? That's a warning sign.

Poor workmanship turns simple fixes into recurring nightmares. A wrong diagnosis means the actual problem never gets solved. Alternatively, bad installation creates new problems on top of the old ones.

For example, wheel nuts have to be torqued precisely to spec after they are replaced. If they are too tight, it can lead to warped rotors and damaged wheel bearings. On the other hand, too loose and the wheels can come off while you're driving. Both scenarios are dangerous and expensive, yet both are completely preventable.

Poor electrical work is extremely expensive to diagnose later. Body panels fitted badly after accident repairs let water in, leading to rust and electrical problems. Rushed engine work can leave vacuum leaks, dodgy gaskets, and incorrectly tensioned belts. These issues all come down to the quality of the repair (and the mechanic who made them).

The Consumer Guarantees Act in NZ says services must be done with reasonable care and skill. If you get burnt by poor workmanship, there is legal recourse, but it's a lot simpler to avoid the problem entirely.

The bottom line for owners is to use quality parts at decent workshops. As for buyers, watch out for missing service history, visible rust, or signs of dodgy repairs. Get a proper inspection and check the vehicle history to save yourself from inheriting someone else's nightmare. For inspection tips, see our guides on
