The 2021 Ford Mustang is one of the most recognizable sports cars of all time: it delivers powerful engines, sharp handling, and an upscale interior. Adding to its line of performance vehicles for 2021 is the return of the limited-edition Mustang Mach 1 fastback coupe. The 2021 Kia Stinger is a top performer, boasts a premium and spacious interior, and stacks up well to Ford’s Mustang.
