Thanks for the welcome. It's an unbelievable car the B3 and the thing I like most is it's extremely rare compared to all those M3's (mine for example is one of 97).
I live in Milton Keynes, Buckinghamshire and currently have no modifications on this car at all. As you can imagine, it's a very difficult decision to alter one of these cars from standard as most Alpina owners look down on this type of thing. As I'm only using this as a second motor, I'm a little more interested in making it stupidly quick. With regards to budget, well, I guess it depends on the potential power increase I might get.
