The SMART FORFOUR NIGHT SKY (2015-17) 5DR NIGHT SKY 0.9T SS 90 EU6 PRIME SPORT is a compact five-door city car, made for easy urban driving and parking. Its four-seat layout offers more practicality than a two-seat Smart, while retaining a distinctive, stylish character. In mycarcheck.com checks, this model has a small sample: three look-ups covering one VIN, so figures are indicative rather than a market-wide picture. The recorded example averaged £4,900 in private-sale value, 64,000 miles and 7,000 miles a year, with one previous keeper. That profile may appeal to commuters, first-time buyers or couples seeking an affordable runabout. Night Sky trim adds individual styling, while its turbo petrol engine suits town use and occasional longer trips. Compared with the Hyundai i10 and Toyota Aygo, the ForFour stands out for distinctive design and a rear engine, but buyers should compare condition and costs before making a used-car buying decision.
