I saw this car for sale on the Race-cars.com site .
Its the same kind of package as the GTD GT40 and can be made to be a pretty good car..
The RCR70 is a different animal being monocoque construction and fully heim jointed , as standard.
My cars are designed to be able to house multiple transaxle options also... the GTD is pretty dialed in to using a Renault UN1 as standard....although the one listed has a 930 I think...
I think its a little pricey at 110k though....that would buy you a beautiful, brand new RCR70...and then some.
