This is at a car lot near me, before Easter it was £1895, now with a sunny bank holiday it is £2195! Passing on my bike so I stopped and asked the man about it. 110k miles, originally silver resprayed grey, nice wheels, upgrade exhaust and the roof has seen better days. He said Z3 s are going up in price, not this one in my opinion. 
Got to admire the optimism.
