 Coming from a Grand Prix GT (3.8 V6) I am getting the same mileage in the city as I am in the SLOWcus (~23 mpg city).  Seems to be reliable though. Trunk unlock is a PITA. Lifetime air filter. Sporty kinda. Get blinker & steering wheel controls confused.  Ceiling compartment (sunshades, garage door) blocks part of view from rear view mirror if your tall (6 ft).
