They're absolute thieving gits, I traded in my 206 GTi 02 plate about 30k miles against the Mk5 Golf GTi in 2009. Despite having the sports mesh grills, 17" GTi 180 alloys, colour coded trim, 6 CD changer, LED rear lights, Sport exhaust and upgraded manifold, lowered on Bilstein dampers & Eibach springs, Drilled and grooved brakes & green stuff pads, full leather interior (which was a rarity in the UK) they gave me a whopping £2800 off the 12k MK5!
I didn't have to accept but wanted rid as I wanted something newer and its the easy option without dozens of tyre kickers and beggers looking at it!
P**sed me off though when I saw it for sale for nearly 5k on there website a few days later...
