Yep. I just hope you don't end up fighting trolls for other brands (*cough* like Lexus *cough) by becoming a brand basher in return..
Anyhow, I've driven: (including friends' cars, but not including test drives)
BMW
Volvo
Mitsubishi
Toyota
Honda
Holden
Mercedes
And anything else, IIRC, I haven't.
I would most like to drive:
VW (been on test drives, but that doesn't really count)
Audi
Porsche (997 911 Turbo, to experience true overwhelming power)
Mazda MX-5 (just to see what the fuss is all about)
Rolls Royce (to see how it is to drive such an expensive, intimidating and large car, not to mention to give a few friends a ride

)
