discount auto parts, auto body parts Buying discount auto parts can be a good decision on your part if you do not mind taking a chance on using replacement discount auto parts that might not be designed or produced as well as the original equipment on your vehicle. If you do not care about this potential problem, then by all means purchase discount auto parts to replace or repair your car or truck. You will save money using discount auto parts and your vehicle will operate just fine. Most auto parts stores sell discounted parts or re-manufactured auto and truck parts such as alternators, transmissions, etc that will work fine for most applications. The only time I would be concerned about using discount auto parts is if I owned a high value automobile or sports car. Then to keep the originality and value of the vehicle you should use only factory replacement parts. The same goes for auto body parts. Stick with factory produced body parts for your top line cars or trucks but use the cheaper body parts for common everyday vehicles.
