I'm gonna break the chain and say Cayman, since I've never read a review of it that suggests it's anything other than one of the best handling cars you can buy, I love the way it looks, and much as I like TVRs, I like to reach my destination most of the time and they're not known for their ability to achieve that goal.
Also, you're all mental. Much as the Scuderia is awesome, the 430 is probably the least attractive mid-engined Ferrari V8 of all time. It's like someone threw a bunch of half-assed Enzo details at the previously-pretty 360. The 458 isn't perfect but at least it's unique (For the record, 360 CS all the way).
From earlier, MG over Mustang (I like Mustangs, but come on...), 350Z over 300ZX, Impreza over Lancia and Mitsubishi (McRae drove it - that's all I need to say), Morgan over Caterham (the Seven is brilliant, the Morgan is sensational and easily the coolest car on sale today).
Then I'd pick Tata Nano over G-Wiz, because I love basic simple cars but still have eyes, and MX-5 over S2000, as long as I get to choose my old NA rather than a new NC. Never really been keen on the S2K's styling and I prefer the NA's simplicity.
