The one below was one of the nicer ones if IIRC


The metallic blue car is the more standard version, called Monte Carlo 220.
The light blue car is a Group 4 replica.
AFAIK they both had Renault 2 litre (12 valve?) engines in them, but could be built to order with many engine and gearbox configurations.
I don't know if any others (of this particular version) were built other than these two.
One of the problems was when the replica/kits were launched (mid 80's - early 90's) the real thing was relatively cheap so it made the kits prohibitively expensive, now the genuine article is more expensive it would be a much better proposition.
Leboncoin were selling tubs on promotion recently for just under 5K euro if you want to have a go yourself... (21T power? Mr Gamblen!!)
Does anyone remember the yellow Honda (or Toyota?) powered example on ebay recently? For sale in the states for about $20K.
