I have two neighbors with them. Both black w/ dark wheels and yellow calipers. One is a wagon, the other a 4 door. One guy is a real motorhead and traded his new 'vette for one, the other is a housewife who uses the wagon to tow her kids to school and back. The both love them. It cracks me up to see this tall blond lady start the thing up, with it sounding all [censored] off while she straps the kids into their car seats.
I don't know if they have done anything to them, they both sound like they have headers and decent exhaust. When they are idling stuff in my (CBS Block) house shakes.
