I've had my Mustang for a few years now. It's one of the most reliable vechiles I own. The performance is incredible. If you plan on getting a Mustang a 5.0 or a 4.6 or even the old 3.8 just plan on having money for a few things (tires and clutches.) I only put about 7,000 miles since I bought it and I'm due for a second set of rubbers and a new clutch.
My favorite features are no cup holders. Why do you need those in a muscle car that huals? the bucket seats are awesome as well
