Completely agree with everyone’s comments that the market is dead. I’ve had mine up for sale since the start of June here and since July on autotrader and eBay with very little interest. Been dropping the price repeatedly. I thought the car would be the sort of thing people were looking for. Owned it for 6 years, good service history, Vanos, bearings, valves, etc. and lots of preventative maintenance done during ownership and 59k miles but even at £13.5k no interest. I’d have been better off neglecting the works and servicing, saving £5k and just sell for £10k had I known.
However lots of cars are in the doldrums at the moment, so because of a change in life circumstances I took the opportunity and bought my dream car that I never thought I’d own - so not all bad news

. Life is fleeting and so it seems if you want a Z4 or your next dream it’s a good time to do it.
