I am picking up my '02 Coupe GT in Dallas this weekend... I am trying to get them to lower the car before i get there and they're giving me a hard time. The car has Skyhook and I've read here that it's not a difficult thing to do as long as they do a wheel alignment afterwards. The technician says he's never done it before and the salesman says that it may void the warranty if they lower it. What gives? Any advice?
