Price and mileage comparison

Estimated market asking price: £6,758. The asking price is £258 below this estimate.

The estimate uses UK dealer asking prices, accounting for make, model, trim, version, age, mileage, fuel, gearbox, body type, driven wheels, engine size and power. It estimates an advertised price, not a confirmed sale price.

The pricing calculation includes 238 adverts of this make and model across different ages and specifications.

Advertised mileage is approximately 24,000 miles higher than typical for a 2018 Smart forfour.

Mileage concern: the advertised mileage is below the last MOT reading; ask the dealer to explain.

MOT

MOT valid until 10 September 2027. 62,608 miles at the last test.

£7,125	62,286 miles

These cars have covered 23,011–62,286 miles, compared with 62,000 miles for this car.

Matching year, trim, gearbox and fuel does not mean matching mileage or every specification. Our estimate adjusts for these differences using the wider market data.
