Took the car somewhere else for another quote today. Less than a thousand bucks! So they don't feel that the support bar is bent enough to replace, and it's a little worrying how they can do they whole job for less than toyota quoted us just to paint the bonnet, but it's so cheap that I'm not asking any questions. It's not damaged structurally and the air conditioner and radiator are fine too, so as long as it looks ok when we get it back I'll be well chuffed.
When it's all fixed up we're going to clean it up a bit (it's festy as inside - full of Tyler's toys and stuff) and go for a weekend trip somewhere.
