The 328i was one, also had a Hartge modified 535i and a 3.0i Z4.
I'd love a TDI A8, but the size of the car is the problem, it will only just fit in my space at work and if anyone's parked badly (a lot of women work there!), then it will not fit, had this a lot with my D2 and end up paying £8 per day in a public car park for the privilege of going to work. I've even come out of work to find other cars parked so close I can't open the doors wide enough, a problem solved in the Boxster by dropping the roof and climbing in
My idea is to have something relatively cheap to run so I can start saving for a 2nd car, a D3 S8, which won't need to fit in the work car park as it won't be used as a daily.
Having said that, I change my mind a lot, a D3 A8 is still a possibility, Audi is my first choice, maybe even an A/S4, A/S6 or an A/S5 even, problem seems to be the transmissions unless I find a quattro, though that wouldn't be a bad thing either.
