Changed a VW polo for a 1 series - that really changed my mind about BMWs (used to hate them). Flirted with Audi for our 'other car' before realising I'm hooked on BMW. Driven lots of other cars, including various mercs, lexus, VAGs, citreon, toyota, peugeot, vauxhall - but nothing else does it for me.
Now awaiting delivery of an F31 330d, and have the E61 520d as the general family car.
Can't see myself stepping away from beemers ever really.
Full history of cars I've used (many belonged to my parents):
1984 VW Polo Mark II coupe - 1.05 4MT still with manual choke. Speedo only went to 100 - and we got it knocking on the end
1988 Toyota Carina II 2.0 GLI Executive
1995 VW polo Mark III hatchback - 1.6 GLX - was a beast to drive when I was still a teenager!

1989 Mercedes 320E
1999 VW Beetle - lime green - very eye catching
