I know that the newer body style would have been much easier to make multiple additional kits from. The Mercury Marauder version would sell well, at least to the Marauder owners. Like the Hudson's have. I am a typical Marauder owner that has to have multiples of anything Marauder related. I would buy 15 to 20 Marauder kits of they made them.
I get the possible rational for making this kit, Revell must have had most of the work done before the Lindberg kit came out. There is no other reason why they would kit such a bland car that is already made by another company.
I would buy a few Marauder kits too. I had a DTR 04 For a week. loved the car. I so want another.
