About the 2006 SMART (MCC) ROADSTER

The 2006 SMART (MCC) ROADSTER is a city car with a 698cc petrol engine. 228 of these vehicles were MOT tested in 2026, making it a less common model in the UK market. It ranks in the top 16% of all 2006 cars for reliability.

With an average of 66,130 miles at 20 years old, 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 £955 per year at current petrol prices of 142p per litre (based on 7,400 miles per year).

What does it cost to own a 2006 SMART (MCC) ROADSTER?

Total estimated annual running cost is £1,380 115/month), broken down as £955 fuel, £20 road tax, £55 MOT, and £350 predicted repairs. Repair costs are moderate, reflecting the 85% pass rate. Keeping on top of servicing will help avoid surprises.

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

Based on the 2006 SMART (MCC) ROADSTER's fuel type, age, and engine size, these are the most likely problem areas to check.

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.
