The Smart Roadster, a quirky two-seater convertible produced from 2003 to 2005, aimed to deliver open-top fun in a compact and efficient package. While its unique styling and go-kart-like handling appealed to some, potential owners in New Zealand should be aware of specific issues and maintenance requirements given the age of these vehicles. It's a car that brings a surprising amount of emotion from such a small package.
• Leaking Roof Seals: A very common issue, especially in older models, leading to water ingress into the cabin. • Gearbox Actuator Problems: The automated manual transmission can suffer from actuator failures, resulting in jerky shifting or complete loss of drive. • Turbocharger Issues: The small turbocharger can be prone to failure, particularly if oil changes have been neglected. • Electrical Gremlins: Wiring issues are not uncommon, especially in areas exposed to the elements. • Engine Issues: Prone to oil leaks and premature engine wear if not serviced meticulously.
WOF tips
• Lights & Indicators: Check all lights and indicators are functioning correctly, including the high-mounted brake light. • Tyre Condition: Ensure tyres meet legal tread depth requirements and are free from cuts or bulges. Pay attention to tyre pressure monitoring systems (if equipped). • Brakes: Inspect brake pads and rotors for wear and ensure the parking brake is functioning correctly. • Suspension: Check for worn suspension components, such as ball joints and bushings. • Rust: With the vehicles being older, carefully examine the undercarriage and body panels for signs of rust, especially in areas prone to water accumulation.
About the Smart Roadster M 160.921 Coupe
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.
