I like to read the descriptions on the cars I buy on occasion, especially the ones I like or are eye catching. Seems to me they select the "best" car from the series of cars they have. The Cappacino for example is a rare gem for its category in that it is powered pretty well compared to most of its own competition (k cars) and is even FR when everything else is majority FF or more rarely 4WD. While I might be wrong in quite a few situations, it seems that for the ones that I cared enough to read the most advanced cars in the series of that era or line of cars will be premium. The RX7 Spirit is mentioned in one of the descriptions paragraphs iirc, and while comparing stats, it makes sense that if I want an RX7 that looks like a bathurst, but looks nearly identical to the superior Spirit, I would want the Spirit instead. Same as the Nissan GTRs, the evos, and I am sure many many others. There is some reasoning to it, and I have been thinking hard about it, and I think they did a decent job on deciding what should and shouldnt be premium. (Of course I dont think the Prius deserves the treatment over cars that should have been remade premium in the first place. I dont see hybrid races happening...)
