Ford's entire Mustang line-up is getting a makeover for the 2013 model year. The Shelby GT500 version, in particular, is getting a new, larger engine that, Ford boasts, is the most powerful production V8 in the world. The GT500 will now be capable of turning out up to 650 horsepower. Top speed is increased to 200 miles per hour.
These cars, SUVs and trucks hold their value better than any others in their categories, according to Kelley Blue Book.
