I'm sure, Image would make some of their Dunlop style wheels for you when the 80 cars are sold. This way you have
no extra costs on the car herself which sounds like a really serious amount for the need to change peripheral parts - and probably a hard way to return
so with the Dunlops the option to go back to wires is still there
you can be save about what you get because Image has the template and all correct measurements (offset, hub style)
and finally the car keeps her value as well as this extra wheels on their own - if anytime to sell separately one or the other.
This Dunlop style alloys look pretty much like old steel ones. Colour free of choice.
I have no further relation to the manufacturer of this wheels, just a thought which I anyway had myself as well, but I also love my black wires, BTW the regular wires are pretty light weight.
