bizarre price for a respray!!!@??

[kenny-d]

Hi, I bought a turn key mx250 coupe from tribute last August, had a couple of wee problems, leaks from rear screen, heavy leaks at top of the doors and a bit of a problem with the windscreen wipers, also had a couple of blisters on the paint.
I put it in to a garage to get it fixed he quoted me £2,500 pounds to fix these issues to include a full respray and underseal with shoot. A bit pricey I thought but [ foolishly ] I'll go with that to get every thing perfect. 4 months later it's just had the front half done [no colour change ] and I've been presented with a bill for £6,430+ vat which takes it up to well over £7,000
Any ideas on my next steps, already told him to f#ck off I'm a pensioner does any one know if I qualify for legal aid, alternative seems to be to scrap the car.
