Not picking on your particularly here Bobby, it's just that yours is the first post I noticed Same applies to the other who have similar cars in their collection...
With an F50, F1 and Zonda in the collection, how do you decide which one to take where? For me, they all fill the exact same brief in being mental analogue V12 supercars, so either you'd find your favourite one and only use that or you'd never really get the chance to 'learn' all three. It's a lovely sunny day, you're going out on some wide empty roads, which does your heart say you'd take?
Same with the 350, the 911, the 22B and the R32: They're all roughly the same size, roughly as quick as each other on the road, similar luggage space etc. What would make you choose the R32 over the 22B, for example? As much as I like the 350Z, I can't imagine anyone would ever pick that to drive over the 997 4L (I assume 997 as you say about the proper gearbox comment) in any occasion.
RS6 as a load lugger I get, and the MX5 too (although I wouldn't say an s/c'd MX5 is much more capable in the rain than the 22B). The Carlton I assume because childhood, as I can't see a single time you'd take that over the Audi.
