E30 M3 vs 190e Evo - 190e, easy choice. As much as I like the way that the E30 looks, the Merc is just better in that department for me.
991 vs 993 - 993 please. They are some of the best looking 911's out there.
MR-S vs MG - MR-S, they are very fun cars, with endless engine swaps or F/I support. Would rather sell it for a 1st gen MR2 though, they are the real lookers in that family tree.
LFA vs R8 V10 - The LFA, it's the modern day 2000GT. The sound, the way it goes (for the times), and the price tag, all reminiscent of Toyota's first master piece.
S65 vs 450 SEL - The 450, it's quick but relaxed. Plus you've gotta love the old boxy Merc's
CR-Z vs CRX - CR-Z. I really like the concept, and have heard they nice to drive. Plus I think they look better.
8-series vs SL - The 8. Great looking, uncommon, V12, and pop up headlights. What more could one ask for?
RS200 Evo vs GT - Not a massive fan of either, but the GT would be my choice out of the two.
Mini vs Fiat vs Beetle: The Mini, it's close with the Beetle, but the Mini has a certain presence to it.
