One of the model clubs I belong to is a model car club, and several of the people in it use the Vallejo paint, with a good clear coat over it.
I personally do not like acrylics, as with enamel I can do a reasonable gloss without clearcoats, which I think is more realistic for the older cars I frequently model. But for customs and more modern cars, the clearcoated ones are nice.
I find car modelers about the most diverse of modelers as far as type of paints. It seems in this area the modelers are about equally split between acrylics, enamels, and lacquers.
