According to Cars.com and current listings, 2007 GT500 examples average in the low $50,000s across a pool skewed by Super Snakes and low-mile cars, with standard convertibles generally trading from the mid $20,000s into the high $30,000s depending on mileage and condition.AdvertisementAdvertisementFair value for an example like this sits close to $24,000 to $38,000, most likely close to $28,000 to $33,000, with the moderate mileage and completed upgrades supporting the figure and the notes below tempering it. At $3,600 with five days remaining, the bidding should climb into that range.2007 Ford Mustang Shelby GT500 ConvertibleBring a TrailerCondition and detailsThe car is a well-maintained, honestly presented example. Finished in Black Clearcoat with white stripes, it runs the supercharged 5.4-liter V8, rated at 500 horsepower, through a Tremec six-speed manual to the rear wheels, with Brembo front brakes, Steeda lowering springs, and a Whiteline panhard bar and rear brace.2007 Ford Mustang Shelby GT500 ConvertibleBring a TrailerIt was purchased new by the seller's father and shows 23,000 miles. Importantly, the desirable reliability upgrades have been done, including a later-model clutch, flywheel, and pilot bearing along with a Ford Racing crankshaft damper, which address known weak points on these cars.2007 Ford Mustang Shelby GT500 ConvertibleBring a TrailerA few points deserve attention. There is a small dent on the hood, which the seller reports did not damage the paint and should respond to paintless repair, along with a scrape on the rear bumper. The modifications are mild and largely reversible, though some buyers prefer a stock ride height. The tires date to 2015, so budget to replace them despite the low mileage. A pre-purchase inspection rounds it out.2007 Ford Mustang Shelby GT500 ConvertibleBring a TrailerAdvertisementAdvertisementThe offerSpecificationDetailMakeFordModelMustang Shelby GT500 ConvertibleYear2007Mileage23,000 milesEngineSupercharged 5.4-liter V8Power500 hp and 480 lb.ft of torqueTransmission6-speed manualDrive typeRear-wheel driveExterior colorBlack ClearcoatInterior colorBlackCurrent bid$3,600, with five days leftInterested in this 2007 Ford Mustang Shelby GT500 Convertible? View the listing here.What makes the GT500 uniqueThe 2007 GT500 was a landmark, the first modern Shelby-badged Mustang and the car that reignited the storied partnership between Ford and Carroll Shelby. Its supercharged 5.4-liter V8 produced 500 horsepower, a staggering figure at the time that made it the most powerful factory Mustang yet and a genuine bruiser on the road. Backed by a six-speed manual and wearing bold Le Mans stripes over aggressive bodywork, it delivered old-school, solid-rear-axle muscle-car character that enthusiasts have come to appreciate all the more as the industry has moved on.2007 Ford Mustang Shelby GT500 ConvertibleBring a TrailerMany enthusiasts consider the S197 GT500 the best-looking of that generation, and the supercharged powertrain is genuinely robust, responding readily to modifications while proving durable in stock form. In convertible form, it pairs that thunderous supercharged soundtrack with open-air motoring, and as an early, increasingly collectible modern Shelby, a clean, low-mileage example like this represents an appealing and still-attainable slice of the breed.My takeThis is an appealing, honest GT500 convertible, and the fact that the common reliability upgrades are already sorted is a genuine plus. The supercharged 5.4 and six-speed deliver serious character, the family ownership and moderate mileage inspire confidence, and these cars have started to appreciate while remaining accessible.
