I've had a lot of different cars although only been driving 5 years.
I had the most fun in the nova probably although enjoyed the RS but thats mainly becuase i'd wanted one since i was at school. Fighting torque steer out of round abouts was quite "exciting" too.
The BMW has also taught me a lot as it's my first pokey RWD (Merc was only a 1.8) and living in our climate you can have equal if not more 'exciting' moments. I used to have a mk2 golf but that was stolen and never recovered but what time we did spend together was good too!
I'm looking forward to the volvo project though so watch this space!
