AS Racer,
I disagree, the GXL (the original starting point on my car) has too much luxo junk in it that you have to strip out (AAS, ABS, Power Steering, All the extra stereo crap, power windows, security system, sunroof, etc etc), vs adding the big brakes and front/rear hubs to a base model, which is a plug and play operation, once you have the right parts. Just my .02$
