Come resale, green will be a tough sell IMO. That said, this is one of the very few shades of green that I find fairly attractive. Unfortunately the sea of grey inside is very disappointing, given the bold exterior.
And then there's the price. Dealer needs his meds adjusted
If you really want to offload 25 large, why not see what deals are out there on nearly new QPs. Even those going through the likes of BCA.
If it's the colour that really flicks your switch and if the dealer is prepared to deal, plus put right any major issues and service it at a main dealer, it may be worth considering. I have a sneaking suspicion that he won't want to do much of the above, if anything. Relying on the colour and mileage to move it. My 10c
