[NO LIFT]

I use a Chevy Impala with police package for my business car. It drives completely different than other Impalas I have had.

No one even notices me.

But, the car drives well enough to keep me entertained, I enjoy embarrassing BMW, MB, Acura, Infiniti etc on entrance/exit ramps and twisties.

Reliable, parts are cheap when you need them.

As far as what customers think, I think they notice whether or not your car is clean (in & out) rather than what it is. If you have a dirty messy car, you don't have attention to detail. And that relates to how they believe they will be treated.
