You will be worse than me! I am getting my by brand new car soon (hopefully) so hopefully it will put an end to too many hours lost trying to find out what sodding sensor has failed now.
I do have a £180 push bike though which has been causing me some problems, currently at 'alfords now getting repaired under warranty.
I really like the look of your 306, I always dreamed of one but never had the bottle. I reckon they would suit my dad nicely but he doesn't like diesels so it would have to be a nice late late model say 2000 with a TU engine.
The 306 really was one of the last fantastic cars PSA made. The current stuff is just too boring and mainstream.
Edit actually Citroen now make very interesting cars but they are too quirky for me.
