About the Smart Roadster M 160.921 Convertible
The Roadster's charm lies in its distinctive design and engaging driving experience. The turbocharged engine, typically a 698cc unit, offers decent performance for its size. However, these cars are prone to certain problems that require careful attention to ensure longevity. The automated manual gearbox, in particular, can be problematic if not properly maintained. These are very sensitive to low voltage and require a NEW battery every 3 years without QUESTION.
