Sure guys F360 and GT3 are wonderful cars, with amazing lb/hp, however they do not offer anything even in the same ball park of $ / (lb/hp). M3 gets you similar hp, similar redline, a bit of a hit on lb/hp and an ungodly hit on $ (and maintenance dollars as was mentioned). Not good comparisons at all
back at ya!
I was trying to focus just on engines as well which was the point of my post.
