Hugo Acosta is a car quality expert at Carma, and spends his days checking over cars in detail. Hugo says you'd be surprised by what people try to hide when it comes to second-hand cars. Luckily, you can use your five senses to pick up red flags.

“It’s all about using your senses to get a feel about the car when you first sit in it and experience it in your life. If something doesn’t smell right, or there’s a vibration to the steering wheel when something’s wrong, or you can feel a line at the edge of a panel and that’s where it’s been masked up for painting, then think twice. It’s all about looking, feeling, vibration, hearing, and smelling.”

Here are a few specific examples from Hugo as you inspect a used car:

Go undercover

Taking a peek under the covers could expose signs that something is off. “Lift up seat covers and dash mats to make sure the condition of the seat is still intact, because people may have put a seat cover on to hide a big hole in the seat or a cracked dash.”

Check the tyres

While some wear is to be expected with second-hand wheels, Hugo says that “uneven wear on tyres is a sign of misalignment or damage that hasn’t been repaired properly.” So check that there’s at least 3mm left on the tyre tread, with consistent wear across the tyre’s surface.

Feel for the thickness of panels

Even in spots where you can’t see, you can feel. “Put your index finger between the panels and if you can feel the differences of panels, that can sometimes mean that the car has been in an accident or the panel has been replaced.”

Varying paint shades or overspray on panels could also be a warning that a vehicle’s been patched up after a prang.

Spot any significant leaks

It’s wise to beware of errant oil or fluid that could be a sign of upcoming costs. “Seals around components are designed to keep moisture out, but at certain kilometres or age these start to wear out. If you’re seeing wet patches or marks and there’s not actually fluid leaking out, that’s just seepage instead of an active leak.

“Seepage based on the age of the car is normal wear and tear. But if there’s a leak, it means something needs to be changed.”

Look out for battery corrosion

A proper look under the hood could quickly help you distinguish a solid buy from a risky one. Hugo suggests checking around the battery terminals for corrosion, “which could mean an electrical fault or that the car may not have been serviced regularly and corrosion has built up.”

Tip #3 when buying a used car: Use a detailed list

While intuition goes a long way as you choose a car, a detailed checklist really helps to ensure you don’t overlook or forget anything important. After all, there are hundreds of small factors that can affect a car’s driving performance and maintenance needs. This is exactly why the team at Carma uses a detailed checklist to ensure every listed car meets criteria across safety, driver comfort, mechanics, interior and exterior condition, technology, vehicle data, and of course the all-important road test.

Explore the used car checklist

You can use Carma's checklist for any car inspection, but here’s something even better - if you’re looking for pre-owned cars in Sydney you can search Carma knowing every car has already ticked all the boxes. It’s an easy way to know that every factor, from electric components to the car’s service history, has been thoroughly checked over and addressed.

As Pete says, “You're probably not going to see a better car presented at the level that we go to, to really experience that car and make sure that once you’re sitting in it that it actually all matches up to the information you have.” Add to that Carma’s 3 month warranty and 7 day return period, and it’s easy to buy with peace of mind.

To sum up

Keep these expert tips in mind as you choose a car, and you’ll be on the right road to securing a car you’ll love driving and owning. And if you’re a little unsure of where to start on your search, our CarMatch selection tool is a great place to begin.
