Quick and easy so far ... like that I can pay with PayPal

The box the Corsa Cat Back exhaust was in was damaged. There was a big hole punched in the side of the box, and it looked like it was dropped, because it was creased in the middle. I talked to the UPS guy and he said that was how the box was, when it was loaded in his truck. I opened the box and checked the exhaust system, no damage and everything was there so I will leave it at that, thank you. V/r, Ricky B. Visco

Very satisfied with overall experience.

Great

Fast, professional service.
