To be honest I've had many leftfield choices, scattered with some conventional choices. I've had a couple of Seat Ibiza Cupra's, Alfa156 V6 SP2, and the IS-F and id argue the 135i was also leftfield to, given how few there are.
I guess I'm in something fairly "obvious choice" now but to be honest I never buy by brand more about what the cars like and if it appeals.
