when i got VZs about 18 months ago i tried to shift on my wheels. they're the Audi version of the Pescara. basically the same but silver instead of titanium and lightly higher offset - got £330ish for them with no centre caps, and they'd been on sale for quite a while. yours are in slightly better condition, mind but if it were my money i'd be saving for VZs (which is basically what i did in real life) and this devalues them
however considering that the Ed30 is a special edition car, i would strongly consider keeping them anyway. you'll need them come resale time if you want to get max value for your car. certainly if you sell in the next 2 years or so i'd imagine that not having the right wheels would devalue the car by more than the amount you get for the wheels, so it is a false economy.
GLWS either way
