When it comes to the 2005 Ford Mustang Convertible, retro isn’t a concept that’s limited to design. This car drives like a relic from yesteryear, too, despite significant upgrades in performance, refinement, and sophistication for 2005. But that’s all part of the Mustang’s undeniable appeal, and with the arrival of a convertible model just in time for summer, it’s more fun than ever to own this American icon.

Ford offers the 2005 Mustang Convertible in V6 and GT trim levels, and the primary differences between the two are price and power. The 210-horsepower Mustang V6 drop-top starts in the mid-20s, leaving plenty of wiggle room for options, while the V8-powered Mustang GT Convertible runs about $30,000 – or $100 per horsepower.

Stomp the throttle of the GT model, and the rear tires streak the pavement with rubber as 300 ponies gallop to the rear wheels, which are suspended by a live rear axle perfect for taking the abuse of smoky burnouts. Just like Mustangs of yore, this new 2005 model dives when you brake, squats when you accelerate, jitterbugs down the road like a rickshaw, and features road feel on par with a Buick. Despite this oddly entertaining driving character, we managed an impressive 18.7 mpg during our test drive of the GT convertible.

On sunny days, UV radiation is just 20 seconds away. Release the Mustang’s outboard roof latches and power the top down to bathe the chrome-accented cabin in sunshine. Even with the side windows lowered, the Mustang’s cabin is relatively draft free. On chilly days, with the windows raised, it’s easy to stay toasty warm. Top up visibility is enhanced with a glass rear window, but as with almost any convertible, huge blind spots exist.

Transport yourself back in time 40 years with the 2005 Ford Mustang Convertible. It’s a literal retro-ride that looks, sounds, and drives like it roared out of the 1960s. Groovy, man.
