The SMART FORFOUR NIGHT SKY (2015-17) 5DR NIGHT SKY 0.9T SS 90 EU6 PRIME SPORT PREMIUM is a five-door city car with four seats and easier access than a two-door runabout. In the UK used-car market, it sits among hatchbacks, aimed at making town driving, parking and journeys less stressful. Mycarcheck.com has recorded five checks covering three distinct VINs, so the sample is limited and cannot establish reliability. The checks show an average private-sale valuation of £6,500, mileage of 33,000 and annual use of 5,000 miles; keepers average 3.2. It may suit city commuters and couples needing rear seats too. The Night Sky’s dark-themed finish and panoramic glass roof give it more personality than city cars, while the turbo petrol engine feels willing in traffic. Against rivals such as the Hyundai i10 and Volkswagen up!, it stands out for its footprint and character, though buyers should check condition and service history.
