Mercedes-Benz SLS AMG: Not liking the looks, has an awkwardly looking monocoque, Gullwing doors too fancy
Macca: Boring on the outside, unimpressive inside
Italia: Never been a Ferrari fan. Strange looks at first sight but 'Hmmmmm' at the second and 'Hmmmmm' to drive as well.
Audi R8: Awesome design, fantastic engine and more than engaging driving dynamics. Looks like an R8, though

Porsche Turbo: Maybe the most balanced machine here.
ZR-1: Never liked GM and any its products.
Dodge Viper: Poised or poisoned?
Lambo: Too fancy.
Porsche GT2: Not as racy as the GT3
Nissan GT-R: Carried Godzilla's name for a reason. Nowadays computerised bullet train.
Lexus LFA: Toned-down, uninspiring design, too expensive, too weak in comparison to Ferrari's V-8 powered Italia.
Porsche GT3: Why get a GT3 when you could get an RS?
Dodge Viper ACR: Still undecided whether poised or poisoned is the more appriopriate word...
Porsche GT3 RS: Racy, great looks, dream of an engine, a typical Porsche grocery getter -> sportscar of choice.
