It's a British Leyland Mini, dating back to 1978 in theory, although the car has been 'completely rebuilt' since then. That includes a reconditioned engine, alloy wheels and new tyres, professional respray, new trims, handles, locks, clutch, grill, bumpers and more.
It also has a long MOT and according to the seller, it 'starts on the button'. More images on the listing, where you'll also find the asking price of £4,250. If that's a little rich, you can put in a lower bid too if you like.
