I would have to say that they would sell more of the Oldsmobile Cutlass kits than they think. Just look at the sales numbers of the 1:1 cars . If they just came out with a 78 or 79 I would be happy !
Also I do not think that anybody has ever produced a rear drive Cutlass in 1/25 or 1//24 scale past the 74 model year , in any medium .
