I live and work in Kensington, so i see my fair share of nice cars
A handful of Ferraris every day, mainly 355's and 360's, then you have your 911's, 911 Turbo's, a GT2/GT3 here and there, Boxsters, M3's, M5's, AMG's, RS-everythings, a Lambo now and again, and of course a Vanquish now and again too

.. without forgetting other Astons, Maseratis, Jags, TVR's, a Corvette at lunch today (that's quite rare, not that i overly mind hehe), Bentley's, Rollers.... pretty damn much everything.... a McLaren F1 but thats in a dealership so doesnt really count..... theres a Ferrari dealership near me too, which, needless to say, is very nice
oh yeah i saw a dark blue Viper the other day with the white stripes down the bonnet - cant remember if its one or two stripes, i was comin out of a club and i'd had a few so memory's a little hazy...

but you dont get american muscle cars too often.
