If your only doing 6k a year you dont need a diesel
Plus for £2k your not going to get a good one, it would be a high miler in which things start to wear out and need replacing (bushes, clutch, turbo) and starts getting expensive to run

You should be able to pick up a nice 1.8T for your price range and try to get the lowest mileage car you can.
Oh and theres an initiation to get into the "elite"
