330d does sound like a good idea Matt plus still possible for a bit of fun as well mate.
You have nothing to lose by putting it up for sale and see what happens, you don't need to give it away so any stupid offers will get the finger.
I don't think you will have any problems selling as it is how alot of people would like a 3 Door to be (ie Hocks or Standard Wheels + sensible power).
Good Luck eitherway
