Cars can begin to decay over time and they’ll need repairs and maintenance to keep them in good shape. The only problem is this cost a lot of money and it’s often a bit more sensible to sell your car and buy a new model.
Of course, you can’t sell a car that’s littered with problems and not many people would want to buy it, except for maybe a scrap merchant. This means that you have to know when the time has come to sell your car before it begins to pick up problem after problem.
Mileage is usually the best sign, and any car that’s been run over 80,000 miles will need some repairs and maintenance work. You may also want to sell the car before it hits 100,000, and by taking the mileage too far, you will put potential suitors off.
