So I finally think I found a body shop that will install my body kit. I just moved to the area, so its not like I know these guys forever, but they have a good customer base and reviews. The question is, should I set my car to the Valet setting, or should I leave it on the tuned or regular settings and not be so worried?? I see so many stories of joyrides gone wrong, or simply abusing the car driving. My car is totally modded and is so much beyond stock, it would be easy for a novice to crash it, and is so loud and tempting to want to try. I need to know what you guys are thinking and would do in similar circumstances. Thanks in advance, I hate saying TIA because at work thats a term for a stroke, and it confuses me:P
