Same as Gar, I'd be hanging onto it for a while. These are very much at the bottom of their depreciation curve I reckon, and there's a lot of love for them over the water (dare I say more than the E60 and possibly the E34). I think the prices are only going up from here on in, so why not stick a cover over it for the winter, then aim to use it a bit come the spring and see where you stand then. That car deserves a trip somewhere next year
