I had an ash black 1 I say bought but stole it from my old boss as a trade car when I worked at bmw. As far as he was concerned it was a piece of shit and got it with heaps of mot and tax for the grand sum of £250 about 10 yrs ago. Spent a couple of hours cleaning it and was a different car underneath all the shit. Sold it to a trader a few days later for £1500

I've had lots of cars like that over the years. Got a fto aswell that was pink instead of red and a very rare manual with a fto plate for a grand and buffed it up and doubled my money. Missed out on a r33 gtr vspec about the same time aswell as I was too slow off the mark when it came in. Boss told me he had sold it to a trader for £2500. Was gutted :-(
Looks like you got a steal with this one and would be a keeper if it was mine. Good luck with it and I will keep an eye for your updates
