The Mazda RX-7 is a powerful vehicle that if maintained well will give years of performance. You can get performance accessories at Auto Parts Warehouse. Their website is at www.autopartswarehouse.com/models/mazda~rx7~makemodel.html. You also need to make sure you are skilled in performing this kind of work to get the best result possible.

You can still purchase a warranty for a used car. Also, sometimes "used" cars are actually still relatively new, and even are still covered by the factory warranty. Ask the sales person about warranties for all cars you are looking at.

Depending on the year of your car, you may be able to take it to the dealership and have the computer chip in your car read. These machines typically know how far you have gone even if your odometer is no longer functioning properly.
