Skyguy007...I'm #0357 and these cars are fast.... No, I have not had it since new (marchof this year) but it only had 12,500 miles when I bought it and I have put about 4,000 miles on it since. My only after market item is the exhaust which is Borla. Oh yes, also bought new tires cause the old ones had dry rot and they are far better than the old ones. Super sticky,smoother ride and not so loud on the pavement. Good Year F1 GS D3's. Z51 handling is the best also I think. Just reading some links about gutting the cats that sound interesting but possibly tricky with sensors so........hmmmmm. Did you go to the 50th in Bowling Green or to Carlisle in Pa. this year? Real good time at both these events. Oh yeah, another thing about the D3's, everyone comments about the crazy tread design on them, kind of goes with the skunk design of the GS (wild and crazy):cool see ya
