Stu, just a thought...I know your track record with cars, and you're keeping them for a few months it seems at the moment! You do a fair few miles, so when you come to sell it, it will still be low miles, but not stupidly low miles, so you wont have that as a selling point. So come to sell, you wont get nowhere near that price you are paying as it's in a common colour with no cup packs. Surely if you want another one, you'll just be best off looking around and paying less, I'm sure there are plenty of mint ones about that have been cared for?
Btw, were you driving through Elm Park tonight, I see a yellow zs going up the hill towards the station as I was coming up to the roundabout? x
