Yea, i don't think they wanted the work, they specialise in insurance work so i think the £360 quote was a "F@@K OFF" price. Gumball has used this company recently i believe.
The car is now going into a proper bodyshop that i've used several times in the past, and he's quoting me £150 cash. He might even manage to get the car back to me the same day, depending on how busy he is.
Chris - thanks for the offer but i'll pass, cheers anyway.
