By far the Prowler is the wankiest one of the two. I've seen a few SSR's up front and personal (mainly because I was sort of interested in one, and I needed something that could either fit or carry a bike), and I actually liked it. Plus, to see what the Prowler should have looked like people should take a look at Foose's Hemisfear.
@Focks, love your paint job. Don't go showing it to Europeans though. Just out of curiosity how much would a full front and side airbrush like that set you back on a car of equal size?
Turning money into memories.
