Thanks guys - I think I'll wait and enjoy the car for a little while before deciding on plans. I've had a remapped MKIV 1.8T which transformed the car, so tempted by that, but not in the immediate future.
First priority is a full detail which should be happening at the weekend - I've got a friend who is a Detailer, and I'm quite into it as well, so we're both planning to giving it the works!

Not quite decided on LSP for it yet though - are there any other white owners who'd like to share what they use?
