I used to own an '05 G35 coupe with some minor mods that I loved. I never raced or revved anyone, although I did have a big diesel truck and a Z06 rev me (laugh). There was one point I considered building up the car to the level of performance of an e46 M3, but that only lasted a week or so, and it would have been for the fun of meeting a goal via tuning. It was a pretty decent car for what I could afford at the time.
I never get anyone trying to race me in the M3, but then again, I'm not really paying too much attention. I'm way too busy enjoy my car for myself.
There seems to be drivers of both types in all sorts of performance cars. Some wanna be douche-bags and look to race. Others like to check out a nice car and give the thumbs up. I get along quite well with the latter....
Sad to say in the next 6-12 months I may have to sell the car for financial reasons due to a change in circumstances. A G37 would be one of my considerations as a replacement.
