It's pretty much always been that way but I think the VIN rule going away is going to shift our perspective just a little.

The classic case is the ITS RX-7. The top cars are 'built into' the 89-91 GTU model...most started out as any variety of versions of the 86-88 car that had smaller brakes, a different front nose, a different intake manifold, a different 5th gear ratio, 16 less horsepower etc...
