Even my ever so slightly
abused Cat C ex plod was repaired at cost of £1850 when bint reversed into it in March...

They wouldn't discuss valuation after the conversation with a lorry on the M6 on the way back from lakes. Managed to go round the houses to get to £1500 ish with 173k during a 'I can't tell you, but if you you ask the right questions you can make a reasonable guess at the value' conversation.
The last repair to mine has cost approx £895 parts/labour/materials. Total time about 6 days, I did most of the grunt work myself.
The electric motor for the field adjustment only clips in. Perhaps popped out with the impact. Also there is a bracket that is welded to the slam panel that supports the ends of the bumper, (available as a sperate piece £25ish). Whipping the lamp unit will soon tell you what's what in there. If the shut line between the bonnet and wing is still true then inner wing prob ok.
If you're otherwise happy with the car, the prob best to repair it, especially as you've almost got it 'as wanted'.
