2007 Ford Mustang V6 Premium 2dr Coupe (4.0L 6cyl 5M)
Except for gas mileage, this is about as much fun as I've ever had driving an automobile. I don't refueling as I only get 20-22 mpg. I did slightly modify the dash panel as the chrome rings around the gauges made the instruments hard to read in some sunlight conditions. The Pony Package suspension with cold air intake and DynaFlow duals make driving country roads near my home a blast!
Suspension, sound (exhaust) and sound (Shaker system).
1. Better gas mileage. 2. Eliminate chrome rings around instruments.
