I rather like the silver GTR, I've often fancied an alloy bodied car all polished up, after seeing an Audi A8 show car with the bodywork polished. It looked fantastic, but you could never keep it looking like that, one trip up a motorway after it's been salted…
An estate car like an Octavia or A4 Avant with the silver vinyl and the windows covered with a mirrored tint would look great. Cooler in hot sunny weather, too.
