About the 2006 Smart (MCC) Roadster

The 2006 Smart (MCC) Roadster is a city car. Our records list a 698cc petrol engine, though engines vary between versions. 228 MOT tests were recorded on this model in 2024, making it a less common model in the UK market. It ranks in the top 16% of all 2006 models for MOT pass rate.

With an average of 66,130 miles recorded at its 2024 MOT tests, Smart (MCC) Roadster owners tend to use this car less than the typical driver. Very low mileage could mean the car has been garaged or used only for short trips, which can cause its own issues like battery drain and moisture buildup.

2006 Smart (MCC) Roadster Fuel Costs

The modest 698cc petrol engine keeps fuel costs low, which is a real advantage for a city car. Expect around 50 mpg in mixed driving, which works out to roughly £1,175 per year with petrol at 174.57p per litre (GOV.UK weekly average, week of 19 October 2026; based on 7,400 miles per year).

What does it cost to own a 2006 Smart (MCC) Roadster?

Smart (MCC) Roadster Reliability Trend

The Smart (MCC) Roadster has maintained consistent MOT pass rates across model years, varying by only 3 percentage points.

Buying a Used 2006 Smart (MCC) Roadster

At 20 years old, the Smart (MCC) Roadster is firmly in budget territory. Purchase prices are low, but check for rust, worn suspension bushes, and electrical gremlins. A full service history is especially valuable at this age.

Common Issues to Watch For

These are typical issues for cars of this age, fuel type and engine size, not faults recorded on this model's MOT tests. Use them as a checklist when you view one.

Coil Pack Failure

Medium risk

Smaller petrol engines are prone to ignition coil failures, causing misfires and rough running. Replacement is £50-£150 per coil.

Rust and Corrosion

Watch out

At 10+ years, check wheel arches, sills, subframe, and brake lines for rust. Structural corrosion is an MOT failure. Prevention is far cheaper than repair.

Suspension Bushings

Watch out

Rubber suspension bushes harden and crack with age, causing knocking noises and vague handling. A full refresh costs £300-£800 depending on the car.

Service History

Low risk

Always request a full service history. Regular servicing is the single best indicator of how well a car has been maintained, regardless of mileage.
