Rented a "new" Challenger RT last week...

the cars look and sound quicker then they really are.

Did you remove the air filter before you ran it--or at least check if it was clean. Got a used 28,000 mile certified GM car last year. Dealer goes on to say all they did to it, new brake pads in front, new wiper blades, steering linage, oil change, etc.

Got the car home an first thing I did was change the oil and filter cause I like name brand 10w-30 oil and a good oil filter. The air filter look never to been changed, what a joke. Dealer act like it was good to go all through winter. It got new tires as well..gotta change the coolant, I keep blowing it off
