Looks like it's had paint on both sides, looking at the wing areas where the bolts are, and it's manky under the bonnet. Surely you'd get the traction lights etc fixed before advertising it..
If the damage was so "light" than it would have been a Cat D.. "The vehicle is repairable but repair costs are significant compared to the vehicle value – including time delays to source parts."
Rather than a Cat C.. "The vehicle is repairable but the costs exceed the vehicle’s value."
That alone indicates the damage was more than the "front corner" at 18 months and 10k miles, what would this have been worth, and for the repair costs to be more than this???
