When you put your car up for sale, you obviously want to get the most money for it. One of the biggest factors in depreciation is mileage. If you have a car with high mileage, however, that doesn't mean you're out of options.
In the UK, any car with over 100,000 miles is considered 'high-mileage'. After that much use, many prospective buyers will question its reliability, condition and outlook on future maintenance. They're generally concerned about the need for frequent repairs or lack of resale potential.
Of course, they have every right to be. Buying a second-hand car — especially on the private market — is always riskier than purchasing a brand-new one from the dealer.
In this guide, we'll tell you everything you need to know about selling a high-mileage car, including how mileage impacts value, other factors to consider, and what you need to do to set a fair market price.
Technically, the best mileage to sell your car is zero (or as close to zero as you can get). But it's actually a lot less about the overall mileage of your vehicle and more about its condition and maintenance history.
A car's components don't all wear down at the same time. Each has its own lifespan. And many vehicle components need replacing long before the 100,000-mile mark.
So, a car with high mileage that has been well-maintained can theoretically be in much better condition than a low-mileage vehicle where the owner avoided necessary repairs or hasn't done regular maintenance.
Certain vehicle components are more impacted by mileage than others.
Let's say your car has 50,000 miles, but you've never changed the tyres and you haven't replaced the battery in three years. When you sell it, your buyer will need to replace these things very soon. So they're buying a car that will cost them a lot more money in the near future.
Even though it isn't specifically 'high-mileage', some of its parts definitely are.
Before we dive into the specifics, let's look at a few quick tips for selling a car with high mileage. Some of these are things you should be doing throughout ownership to ensure your car retains as much of its value as possible.
These tips are important for anyone who wants to sell their car, no matter how they sell it. But they are especially important when you're selling a high-mileage vehicle, since maintenance by that point is practically guaranteed.
Market dynamics play a crucial role in how much you can ask for your car. Before pricing and prepping your car for sale, ask yourself these three questions:
We're going to go out on a limb here and guess you aren't well-versed in up-to-the-minute auto market dynamics. That's why it's best for you to take your car to an authorised garage before you sell. While they look over your car for potential problems, ask for an appraisal.

Properly preparing your car for sale will help you justify a higher asking price. When interested buyers look at your high-mileage car, they want to see it’s been taken care of and is in good condition.
Here are a few things you can do:
Think of it this way: Would you want to pay a high price for something that looks heavily used? Or would you ask for a lower price simply based on aesthetics?
Most of these fixes are £50 each or less. But they're the difference between your buyers thinking,
versus
You'll have to do some extra convincing when you sell a high-mileage car no matter what. But, if everything looks pristine, some of its value will speak for itself.
When you price your car for sale, you have to consider where you're selling it and its overall condition. It's an inexact science, and you might find yourself surprised by some of the offers you receive.
If you sell your car privately, you can set a higher asking price. Don't be surprised if you take it to a dealership or submit your info on a car buying site and receive a lower offer.
You also have to be realistic about the condition and age of your car. As a rule of thumb, you should never expect more than half its original value for a high-mileage car. Cars depreciate fast as it is, and high mileage only exacerbates the problem.
Selling a damaged car (or selling a non-running car) will diminish its value significantly. Conversely, a nice-looking one with few or no structural/aesthetic flaws will sell as if it had fewer miles.

Most dealers will either look at your odometer and give you an unfavourable offer or turn it away immediately. If you want to get the most for it, your best bet is to sell your car online.
Whether you list it on a classified site (AutoTrader, Gumtree) or a marketplace (eBay Motors, Facebook Marketplace), it all starts with the right ad.
Here are a few tips for creating an ad that gets the right buyers to click:
If you're unsure where to place your ad, we have another article where we break down the best websites to sell your car. It includes a recommendation for just about every circumstance.
An interested buyer will find out about your car's mileage anyway, but upfront transparency will save you a lot of hassle dealing with buyers who aren't interested in a high-mileage car.
When you create your listing, be sure to include all relevant information about its mileage and history, including:
If your vehicle has high mileage and is also unroadworthy (i.e., it hasn't passed an MOT test or has been declared a write-off), you must explicitly state this. It is a criminal offence to sell an unroadworthy vehicle without letting the buyer know.
Just because your car has a lot of miles on it doesn't mean it's all bad! Especially if it's in working order and has been nicely kept, there's still a lot of value in it.
Highlight the good elements by pointing out features like:
Some buyers will see these factors as a reason to buy your car rather than avoid it. They'll see it as a great deal considering the mileage and lower asking price.
You really have to zero in on the benefits during negotiation. Expect more pushback and scepticism from buyers when selling a car with high mileage.
Here are some common objections and ways to counter them:
Counterargument: "The car has a lot of miles, but it's in great condition for its age. Since I've recently replaced many of its parts, you'll get great value for your money with all the features and low running costs."
Counterargument: "This car has been serviced regularly and is up to date on its MOT. These documents certify it's in working order and safe to drive."
Counterargument: "High mileage doesn't necessarily mean a car is unreliable — in fact, some of the cars you're looking at with fewer miles are less reliable. It's all about upkeep, and I take good care of my car."
How you finalise the sale depends on the type of buyer you're dealing with. If you're selling your car to a dealership, they will often take care of the paperwork (bill of sale, V5C transfer) for you. If you're taking it to the private market, you handle those things yourself.
Here's a checklist with everything you'll need to do to successfully transfer ownership:
Don’t fall for car selling scams. Do not (under any circumstances) transfer ownership or hand your buyer the keys until the money is safely in your account. If you're selling for cash, have it verified at a bank. If it's a bank transfer, wait a few days for it to clear.
With the right strategies and a bit of patience, you can get top dollar for your car — even if it's seen better days.
Just remember to be upfront and transparent with potential buyers. Highlight the car's value and features and be prepared to counter objections during negotiation.
By following these tips, selling a high-mileage vehicle can be easy and profitable.
Somewhere between 30,000 and 50,000 miles, you'll start to see the first real problems with the car. But that all depends on how the car is driven and how well it's cared for. Someone who frequently speeds and slams on the brakes will start having problems with a car earlier than someone who follows the speed limit and brakes gently.
The same goes for maintenance — regular oil changes, tune-ups and other preventive care will help keep a car running smoothly for a lot longer. The mileage of specific components often plays a more immediate role in performance than a car's overall mileage.
Accident history can also play a role in this. There's often unseen damage after collisions that isn't addressed right away. A few years later, that damage can start to manifest itself in mechanical issues.
So, generally speaking, it's not so much about the mileage but rather how well a car has been taken care of. That said, excessive wear and tear will eventually catch up with any vehicle no matter how meticulously it is maintained.
You can sell a car with 200,000+ miles any way you like. But you have to understand its value will take a huge hit. The best way to maximise the sale price is to gather as much information about the car's maintenance and condition as you can. This will help give potential buyers a better sense of what they're getting for their money.
To most, 'high-mileage' means 100,000 miles or more. The average person puts between 12,000 and 15,000 miles on their car every year, so 100,000 miles usually means the car is 8-10 years old. Most engines will last longer than that, but high mileage can cause significant wear and tear on the engine. It's important to properly maintain your car at regular intervals (every 5,000-7,500 miles) to minimise any damage that might occur from excessive use.
There's grey area in UK law regarding whether you can legally change the mileage on your odometer. Altering the mileage on a car is legal. But it is a criminal offence to sell a car with altered miles without explicitly disclosing that to the buyer. Sellers can also be prosecuted if the buyer can prove they marked down the odometer solely to bolster the sale price of the car.
