When is enough enough when repairing your car?

Not everyone wants or can afford a new car. But if used cars are less available, the price of those used cars may go up.

And, car makers have cut their inventories. There are fewer trade-ins, which makes your used car more valuable -- and provides incentive for you to keep it in top shape.

Used car experts say the key is avoiding costly repairs in the first place.

"If you stay ahead of your car, it literally can run forever," said Jack Nerard of Kelley Blue Book. "Probably the least read book is the owner's manual of any car. Almost no one cracks that one open and there are so many good pieces of advice in a book like that."

To avoid costly repairs as your car ages:

• Change oil frequently. Consider synthetic oil.
• Change your coolant.
• Keep your tires inflated and your wheels aligned.
• Keep your car washed and waxed to avoid corrosion.

If you have to replace an expensive part, consider rebuilt parts, but make sure you get an ample warranty. You can also replace upholstery and ripped carpet for much less money than you'd shell out buying something brand new

Nerard said maintaining a car "and then repairing is less expensive than buying a new vehicle."
