The good: The 2013 Ford Mustang GT produces massive power while getting reasonable fuel economy. Sync is, as in other Ford models, an excellent means of integrating phones and music players, and offers very advanced app connectivity.
The bad: The radio interface is clunky for browsing a connected device's music library. Paddles would have made manual shifting easier with the automatic transmission.
The bottom line: The 2013 Ford Mustang GT looks very cool and churns out tons of power, yet its reasonable fuel economy, easy driving manners, and useful cabin tech make it a fun daily driver.
