In general, you can expect a conventional car to last for around 200,000 miles. If the vehicle is especially well maintained, it might reach 300,000 or beyond.
Choosing a car brand and model with a reputation for reliability and longevity will improve your chances of achieving a higher-than-average mileage. Washing the car regularly, staying on top of servicing and maintenance, completing small repairs quickly, and driving carefully can also significantly extend its lifespan.
In some circumstances, yes. Many cars can last over 300,000 miles - and most modern vehicles are crafted with high mileage in mind. Properly maintained, well-built cars can see 300,000 miles, which roughly equates to 12 years on the road.
An especially reliable car that is carefully maintained, routinely serviced - and avoids serious collisions could potentially reach 500,000 miles, but this isn’t particularly common.
The main factors affecting the lifespan of a car include how well you take care of it and the make and model of the vehicle itself.
When choosing a car, you should opt for something reliable and fit for purpose. Ensure that you stick to a regular schedule of maintenance to help prevent mechanical issues and maximise your vehicle’s lifespan.
Cars with over 150,000 miles on the clock can be considered ‘high mileage’, but what is a good mileage on a used car? If you’ve been shopping for a used vehicle, you might find yourself wondering whether it’s worth buying a high mileage car.
So long as the vehicle has been well cared for and has no serious mechanical faults, a high mileage car could provide you with years of reliable use.
Whilst mileage can affect value, it isn’t everything - and if you can prove that the car was well cared for, this will increase your chances of selling for a reasonable price.
High mileage can cause the piston rings on your car’s engine to fail; this is one of the most common issues among high mileage cars. Look out for signs such as excessive oil consumption, grey or white exhaust smoke, and loss of power and engine performance. Make sure you have the piston rings replaced when necessary.
If a car hasn’t been properly maintained or has used poor quality oil, the engine might burn through oil more quickly than it should. Transmission failure and water pump leaks are also more likely after the 100,000-mile mark.
The timing belt can fail when your car reaches anything over 60,000 miles. Rust can also spread, which can eat away at your vehicle’s metal. Excessive rust can seriously damage your vehicle – and if it spreads to certain prescribed areas, it could also lead to MOT failure.
