The wife is happy once more.
I couldn't source a replacement indicator lamp from any breakers so ended up paying Honda just over £49.00 for a new one. My friendly bodyshop repaired the chipped mirror casing without it needing to be taken off the car, sprayed it and replaced the innards.
He also fitted a set of bumper & door protection strips I bought recently on eBay, all for £50.00.
The cheapest replacement wing mirror I could source was just over £100.00 and would then need spraying. Overall I must have saved a few quid. All I need to do now is keep at her to fold the mirrors in each time she parks.
