My local dealership group, Pulman, have 3 GTDs on offer at the moment, 63 plate 5 door manual is £24k,DSG same price, 5 door DSG is £24.5k. No mention of options, so i'd expect mine to be up for £24k right now if they had it available for sale, £21k should be achievable as a p/x if the dealership isn't wanting to be too greedy. If I wanted to hang on until the next plate, i'd probably expect £1500 less (£200 a month depreciation for 5 months after a plate + an extra £500 off at plate change month after year 1 right through to year 3 is about right).
