I think the GTI is pretty much the ultimate all-around car when you consider all of the usual important criteria... cost, utility, sport, mileage, luxury. They let the world know that you are practical but not boring, but more importantly they excel at almost everything. The TT is a sweet car but it's for chicks, kind of like a Z4. That Mercedes is hideous and boring IMO.
