Hi iv got a golf rolling stones i no what ya mean about the interior but if your gonna get rid your taking away the an origanal part of the car i was advised not to do it with mine especially if your gonna sell it in future.
Yeah I'll second that - I'm even keeping the wheels and stuff on mine in case I want to sell.....
When I bought mine this year, I went through loads on autotrader. If it mentioned any modifications, the NEXT button was stabbed, without too much thought.... And I'm a modder!

So If you do want to change your seats, keep the originals...
