It's not a lot, but it isn't nothing.
I would love it if a car would have like the same (or almost the same) 3d-models of 1 car, and make different types of it.
Diesel version, Petrol version, 1.6, 1.8, 2.0, 1.8t etc. etc. Hatchback, stationwagon, 5-door, 3-door, sedan etc. etc.
They did something like this in NFS Porsche IIRC. (one of the best games ever made)
