Car issues or some damage can have a profound impact on your vehicle’s resale value. These types of problems can even impact your resale value more than lots of kilometres on the clock or the year model of your ride.
Your car will still have some value, no matter how damaged it might be. Let’s take a look at how mechanical issues and damage can affect resale value and how you can get a good price for your old car despite its flaws.
Effect of Mechanical Issues
Mechanical issues can decrease your resale value by hundreds or even thousands. If your car won’t even start, you’re probably not going to find many buyers interested at all. And it’s not just the big problems that scare people off — something as simple as worn brakes can knock down your car’s value too. Buyers tend to read that as a red flag: if you skipped brake service, what else did you skip? Oil changes? Fluid top-offs? That’s the kind of thing that makes them walk away, or at least lowball you.
Bodywork Damage
Bodywork damage like dents, scratches, or a cracked windscreen is a clear sign that the car was in some type of collision or accident. With most vehicles, bodywork damage can also be an indicator of some mechanical damage. Vehicles that get into an accident usually suffer mechanical damage because of the impact of the collision.
Other types of damage, like scratches or rusting, can indicate that the car wasn’t properly cared for. This kind of neglect can point to a lot of mechanical issues down the road.
It is also very expensive to get bodywork damage restored. Even if these flaws are only surface-deep, it will still cost a lot to get the car back into shape so it won’t look bad.
Because of the likelihood of mechanical issues and the cost of bodywork repairs, your resale value for these vehicles can drop by up to 20%.
Tyres and Wheel Condition
Tyres are one of the first things buyers check, and they’ll spot bald or uneven wear before they even open the door. Kerbed alloys are another giveaway — it tells buyers the car hasn’t exactly been babied. And since a full set of new tyres isn’t cheap, don’t be surprised if buyers use that as leverage, knocking more off your price than the tyres would actually cost to replace. Bent rims or an alignment that’s off can also make people nervous about suspension damage, especially if there’s a chance the car’s clipped a kerb or hit a bad pothole. Worth knowing too: if you book in a roadworthy check before selling, tyre tread depth is usually one of the first things they look at.
Engine Light or Dashboard Warnings
For most buyers, a check engine light staying on is an instant dealbreaker. It’s a signal that something’s wrong under the hood, and depending on what’s actually causing it, you could be looking at anything from a minor sensor fix to a full engine replacement if things have gone seriously wrong.
You can visit your local mechanic and get a diagnostic scan done. If the report indicates minimal issues, then it can serve as encouragement for potential buyers. However, for the most part, that little light will make it very hard to find any interested buyers.
Interior Wear and Damage
Ripped upholstery, stains, broken handles and knobs, a layer of dust, or a bad odour can all affect the resale value of your vehicle. Upholstery is a lot more affordable to repair compared to bodywork issues. The repair process is, however, still quite tiresome, and there are so many used cars out there that are still in good shape.
A poor interior can also indicate that the car was neglected and can be a warning sign that something else is likely wrong with the vehicle.
Ultimately, these types of damage will also knock down your resale value.
Missing Service History and Documentation
Even a car that runs like a dream can lose value if there’s no service history to back it up. Buyers want proof that oil changes, timing belt replacements, and other routine maintenance actually happened on schedule — without that paperwork, they’re just taking your word for it. And most people won’t. They’ll assume the worst and price accordingly. The same goes for missing manuals, spare keys, or roadworthy certificates — small things, but they add up to buyers wondering what else might be missing.
Getting the Best Price for a Damaged Car
Even if your car’s got mechanical issues or visible damage, there are still ways to land closer to a fair price. Being upfront about the car’s condition from the start saves everyone time — nothing kills a sale faster than a buyer showing up, spotting a problem you didn’t mention, and walking straight back out. It’s also worth getting a couple of quotes before you commit to anything, just to get a feel for what’s reasonable. Prices can swing a fair bit from one buyer to the next.
Beyond that, it’s worth doing the maths on repair costs versus what the car would actually sell for once it’s fixed. Sometimes a car just isn’t worth saving — and that’s okay. If it’s badly damaged or doesn’t run at all, you’re usually better off going to a specialist buyer who deals specifically in damaged or unroadworthy cars. They’re set up for wrecks and parts recovery, so they can often offer more than a private buyer ever would.
