Buying advice: Ask the test driver!

Essentially, I will go ahead and test drive (or have test driven) any car you need me to. Here's basically a list of the best cars in each category:
Superminis: Renaultsport Clio 200 Cup (US: VW Golf GTI)
Hot Hatches: Ford Focus RS (US: Mini Cooper S)
Sedans: Vauxhall Insignia VXR (US: Mitsubishi Lancer EVO X)
Supersaloons: Vauxhall VXR8 (US: Cadillac CTS-V)
Affordable Sports cars: Mazda Miata/MX5
2-seat Sports cars: Audi TTRS (US: Nissan 370z NISMO)
Off-roaders: Range Rover Sport S/C or if you're on a budget, Jeep Grand Cherokee SRT-8
Ultra-Luxury sedans: It's a really, really tough choice. Mercedes S65 AMG, BMW 760li, Maserati Quattroporte, or if your shirt is made of leaves, Lexus LS600h
Minivans: Vauxhall Zafira VXR, or if Mercedes still makes the insane R63 AMG, the only way you can powerslide a refridgerator.
Supercars: You know, you can't go too wrong here. four-pots, go Ariel Atom. V6, go porsche 911 GT2 RS or 911 Turbo S. V8's, go 458 Italia, Atom V8, SLS or Koenigsegg. V10, go Gallardo LP 570-4 Superleggera. V12, take the new, crazy Lambo Aventeador, or any sort of Pagani. W16, well, i think you can see where this one's going.
Crazy doors: Mercedes SLS, Lambo Aventeador, Koenigsegg CCXR or Agera.
Speed breakers: Veyron, Koenigsegg, SSC, or wait a year for the new 300 MPH Dagger GT. Anything else you want to ask, I'm open to questions.
