[Closed] Random Q - How much for a new bumper for a Corsa ?

Last night stuipidly I drove in to the back of a 2007 plate Corsa at a roundabout.

She set off then stopped, I was looking at the traffic coming and not her, moved and straight in the back. When she got out she actually apologised and said she went but then changed her mind..

Anyhow my car is fine, but her Corsa has a big dint in the bumper about 30 cm long and about 10cm deep. All the panel gaps etc are how they should be.

She is getting a quote today for repair so hopefully I dont have to go through insurance.

I rang a Vauxhall dealership earlier and they suggested £500-£600 for a new bumper and respray ! How much should this really cost at a more decent garage?
