What are Speedlines worth

Got a new 200 being delivered to me on Saturday with satin black speedlines and I'm thinking of changing them for some OZ wheels and tyres, what should I get for the wheels and tyres.

The car was a cancelled order so not my wheel choice.
 
Unfortunately they seem to be attaining less of a premium every set that goes up for sale.
 
I might be interested depending on price/ location as i need a set of tyres this week - prefer the black wheels to the anthracite ones - any idea on price?
 
I'd be interested too depending on location stick a price up then see who makes the best offer.
 
I can't see how they've ever demanded so much money.

The lower prices now are a lot more realistic. They're not eye catching wheels IMO
 
Depends on condition.

A mint set should be worth £500+

People sell used/marked sets for £300+, but a proper refurbishment is £60 per wheel.
