If you have a 1.8T I'd spend it on a remap... thats if you don't mind telling the insurance (or not!) advantages are obviously greater perforamnce and even more economical. Although not sure if this puts more stress on the turbo.
Or what ever model, with summer coming up (and its going to be a good one!), spend some of it on the SmartTop module (£220). Extremely please with mine and too are a number of others on here. Lets you open/close the roof via original remote, or just the windows, also its not necessary to hold your finger on the button to operate the roof. You can operate the roof whilst driving upto 25mph (at your descretion!) amongs a number of thers functions that can easily be turned of and on via a certain sequence of lock and roof buttons.
