Yes but they're a workshop, they'll have insurance, and they'll get it sorted and fixed without you having to do anything.
Most workshops won't just give you cash and say "Hey, Go fix it yourself"
For one, you'll need to ring around and get quotes, they wont just go "thats about...$500, here ya go" And if you don't get a quote cheap enough who says they will even give you the cash?
If you didn't make a claim and they decide they don't want to give you cash, you don't have a leg to stand on and you're completely ****ed.
