208,000 miles on my V2. As I read these posts I guess it was the 1.7. I never modded it. Modding any car leads to problem solving, which is fine as long as one likes problem solving. Same set of circumstances as yours. I was redlining until I sold it without concern. A quick 140 to 160 on occasion.
Someone on this forum has 300,000+ miles on his. It would be interesting to know if he is on his first supercharger.
