The Ford Mustang is back for a seventh-generation with the S650 lineup. However, the newest Mustang stands on the shoulders of the S550 model, which means tons of used Mustang options for bargain-hunting speed freaks. Better yet, the post-facelift S550 Ford Mustang GT with the 10-speed-automatic transmission might be one of the best performance bargains on the market for a stock, sub-4.0-second dash from 0-60 mph.

A 2018 Ford Mustang GT with a 10-speed automatic transmission can sprint from 0-60 mph in less than 4.0 seconds– but just barely

In 2018, the Ford Mustang GT got a midcycle update with a new look. However, Ford’s engineers also dropped the six-speed automatic gearbox. In its place, the Blue Oval installed a 10R80 10-speed automatic transmission.

The six-speed MT-82 manual transmission remained in the lineup, giving purists a grab-a-gear option. Still, the three-pedal Mustang reported improvement in its 0-60 mph bragging rights. Specifically, the 10-speed pony car hit 60 mph in under 4.0 seconds, a feat typically reserved for Shelby-badged models before. 

However, the 2018 Ford Mustang GT’s real-world acceleration figures vary. For instance, testers managed to clock a 3.99-second run to 60 mph from a standstill. That data is reportedly backed by a Racelogic Vbox II unit and its GPS tracking, per Cars.com. However, other reviewers reported runs as quick as 3.8 seconds with traction control off and a 2,000-RPM launch.

Fortunately, the sixth-generation Ford Mustang model is something of a performance bargain for car shoppers at the moment. According to Kelley Blue Book (KBB), a 2018 Ford Mustang GT has a fair market range of around $23,607 to $25,954. However, prices may vary due to factors like location, title status, trim, and mileage.  Better yet, you can find a used S550 Ford Mustang GT on MotorBiscuit’s car-buying tool.
