Not being funny mate - buy it, take it, fail it, fix it.
I bought a Driver (blind sort of) and took it for a mot and now have a fix list, my time and effort to put it right, I will add my hourly rate is most likely a lot more than VW labour rate, so answer to yours is about £1000 Inc parts and labour, won't do vat. Sorry to be vague mate but what needs doing?
