When I was in LA this past summer, I saw a black G35 coupe come up behind me on the freeway. I noticed he had a big front mount intercooler. I didn't try to race him as there was a lot of traffic and no good opportunity. Anyway, he cruises past a couple lanes over then just gets on it. He goes from 65 to probably 100 in no time. Beware, apparently G35 coupes with turbo kits have some crazy topend power.
Just thought I'd share.
