B6 s4 wheels. How much

Good clean sets are 400-500 still depending on the tyres, yours look like they need refurbing so thats 200 quid straight away. I'd be happy with 300 for them. Put them on ebay, they seem to sell on there
 
I've seen them go quite high on eBay so take a chance

As above I've also seen near mint ones go without tyres near £300 and good tyres at £500

But as its non standard colour and needs a refurb you'll require to find someone who wants though

Remember Ebay you'll loose 10-20% in fees etc

Good luck
