I decided to go for a 325d instead of the 330d, as it was the only one I could find with cream interior and in my price range!
In all fairness, I think you'd be far from disapointed with either of them!
I sometimes wish I had bought a 330d, just for the sake of it. But 90% of the time I don't even use all the power I do have anyway, so I don't think I could really justify the price increase to of had the 330d
