Need a new front wing...

As title says. 

The in-law's Dacia Sandero has been backed into by a van or thumped at some speed with a trolley in the local supermarket carpark. 

She's adamant that she wants to take it to the dealer to get replaced, however I'm trying to source a perfectly good 2nd hand one online - painted and ready to fit to save Renault gaining £££'s when the actual new front wing can be bought for £70. 

Can anyone recommend a site that allows you to search local salvage yards, or a place that ships salvaged parts across the country?

Had a look on eBay but they're all primed rather than ready to fit. 

Thanks in advance.
