I would think that in sales, you want to project that you're not some fly-by-night saleman, but also that you don't have obscene profit margins.

As such, these are the vehicle I think paint the right picture:

Chevy Impala
Cadillac CTS
Ford Taurus
Lincoln MKZ
Anything 4-door in the middle of the Volkswagon/Audi lineup

I didn't put any Japanese cars on their because I can't think of any that are big enough to be comfortable for four grown men without also being pricey.
