So how is it any different than buying FM5 in general? You paid $60 to play with cars and tracks that were in FM4. The same goes with FM 4 to FM3. FM3 to FM2. FM2 to FM1. I doubt anyone is disagreeing that 10 all new cars would be welcome, but to ignore the development and costs behind DLC is a massive oversight and a poor assumption to make. It doesn't matter if the cars were in FM4; they still needed to be updated for the new physics and graphics engine, as well as integrated into all of the features of the game.
