I bet it will handle really well now too.
Take a really well balanced sports car, stretch it, make it heavier by throwing in a big V12, and mate it to an automatic transmission. Sounds like a nice recipe for turning it into a cruiser. Oh well...as long as the guy enjoys it. Me? I would much prefer to just drop in a Porsche 3.6 or 3.8, and turn it into a super Boxster instead of a Boxster Limo.
