Pretty sure the rail isn't bent, but I'm no expert.
I took it to two repairers today after work, neither could give me a quote or a definite opinion on whether it is a write off or not.
The first said he wouldn't give me a quote because it's going through RACV and he's not a recommended reparier for them, and he also said from past experience they are pricks to do work for. I asked his opinion though and he said it's possible that it's a write off. He estimated ~$100 each for second hand bar, guard and door, ~$600 for paint work, and the labour for that would bring it close to $1500. Then there's the damage to wheel/suspension, so it would depend on exactly what has happened there.
The second guy looked at it and thought it wouldn't be a write off just by looking at it, but couldn't tell me for sure without putting up on a hoist and having a proper look at it.
So I guess I'm just going to have to wait till I have it assessed by RACV's repairer to see what's going to happen. It is booked in for Monday.
