I have the head unit I'd definitely be taking back, £100 worth of the side and front indicator bulbs, there's nothing I can do about the new brake pads and discs I had fitted some 2000 miles ago, my plates, I'd like to keep the steering wheel too and gear knob but I bet that won't sit well with the insurer? I had an inspection 1 and an oil service done, the tyres were still good, around 4mm left on rears, and a host of other little upgrades like stainless steel lines and so on that aren't easily removed if I go to BMW to collect the bits I can remove, along with personal possessions still in the car..
I suppose if there is a private seller out there with a good example who is selling it for less than 10k I'd be in business. It doesn't "have" to be a manual, but I'd prefer one. It doesn't "have" to be a convertible either, but again, I'd prefer one. Just has to meet my base preferences of condition and colour combo really I guess.
