I've built one sofar..Still work in progress, but no longer a member here. Stroker big block, GV OD unit, suspension bolt ons, and 13" Baer brakes with hydroboost all around. The owner and I recently toured XV. Very nice product, but if you really want performance, Level 2 is the choice, and you should start with a fresh unibody. Level 2 requires removal of engine, refinishing the engine bay (unless you want to see burnt paint), refinishing of the trunk(same as engine bay), and permanent modification to the unibody. Also, if you've already bought performance braking for the car, you will be selling it, as XV will not (I was told for liability issues) offer their kit to fit any other brakes than what they sell. I also dont like the charges associated with transporting your car to Canada for the work to be completed by their shop. ($2/mile) Level 1 stuff can be closely duplicated with currently available product from other sources if it's installed and set up properly, for less money. The fact that the kit is just that, a matched kit, is a great feature, but it's top dollar for basically a factory suspension. Air bags are great for show cars and cruise nighters, but if you plan to really drive the car to it's new limits, I wouldnt use them. They are cheap and can raise of lower ride height, but they are not a supple road race suspension. That Level 2 will give the car handling like nothing the muscle cars ever had, and will rival any production sports car on the road. But in my friend's case, he is looking into possibly buying a complete car from XV, as opposed to paying to modify the car he just did most of the work on.
