BBS Speedlines 19 x 9 - What are they worth?

[Palmer]

I've got a full set on my A8, fitted with Khumo tyres, all have lots of tread left, dont think they were that old when i bought the car.

Im going to be ordering my new wheels within the next couple of weeks, and was wondering what these are worth? Seen varying amounts on ebay from 400 right upto 1200.

All wheels are kerbed on the outer rim and would ideally need a refurb. But all run straight and true.

Anyone know what they are worth or would be interested??
