Ah, to heck with the XLR, I want to know more about the Lightning. Is it stock or has it been "tuned" a bit? Pound for pound, one of the best vehicles I have ever owned - and I have been lucky enough to own two. I had a black 99 and a true blue 2002. The 02 model in stock trim would have roasted our XLR off the line and all the way to 140. After receiving an infusion of parts from JLP, it was an 11 second quarter miler that would (and still could) roast any of the "V" series vehicles. Nothing like rolling up to a stop light in a 5,000 lbs. truck and watch the guy in the 3,100 lbs Vette get a bit nervous!
