I brought mine 7 months ago from withams you can get them for about £1200 and less but these will be real dogs with many many parts missing and are probably only good for breakers.
It's hard to find a decent one or even a complete one,I've only seen 1 that was complete moted taxed and road registered it sold on eBay for £4000 about 2 months ago.
My snatch sounds like it has the same sort of problem yours had, although i cant get it to start at all. I do have an MOT on it tho from prev owner despite its lights not working and the engine not running and not having a hand brake fitted lol
