2002 Ford Thunderbird
The 2002 Ford Thunderbird marked the revival of a classic nameplate, offering a retro-styled roadster with modern amenities. It was only offered with one engine option: a 3.9L V8 engine producing 252 horsepower and 267 lb-ft of torque. It was also only offered with one transmission: a 5R55N 5-speed automatic transmission. Owners often praise the Thunderbird’s distinctive styling and comfortable ride. Criticisms typically revolve around its limited practicality (small trunk space), some reliability concerns, and higher maintenance costs associated with a niche vehicle.
