Is a 2008 Ford Mustang Shelby GT500 worth buying?
Yes the 08 Mustang Shelby GT500 is a fantastic car, but I also agree that an older rousch, cobra, or saleen mustang that is modified would be equal or higher horsepower, and would cost about half the price. You also might consider the 2009 Dodge Charger SRT-8, 2010 Chevrolet Camaro SS, 2009 Chrysler 300C SRT-8, 2009 Chevrolet Corvette Z06. If you are chasing horsepower, then get the shelby or the corvette z06. If you want speed with high reliability, get the charger or the 300c. Also, look at the cadillac STS or STS-V series, as these have great horsepower and great luxury.
