Hey guys this isn't really "off-topic", is it?
I always liked the "shark" but tales of the maintenance complexity/expense scared me off.
However, I have seen a couple of gutted 928 race cars that were very cool. A "928R" kind of street/track concept would work for me...lose some poundage and lose a lot of the luxury doo-dads such as the vacuum locks and non-essential computers.
I have a video of a blown 928 hillclimb car that is pretty friggen fantastic. Torque does wonders for an overweight car.
