What is a good car to build a good car audio system in?

Im looking for a car that has good acoustics, placement options for speakers, and things like that for which I can install a great car audio system into. Speaking to experienced car audio installers, Im looking for things like for example, a car with a good trunk to bring out the low frequencies in the subwoofers, or something with the speakers placed in optimum positions for best sound. Know what I mean? Doesnt have to be newer, any year would do.
