The SMART FORFOUR (2014-19) 5DR HATCHBACK 0.9T SS 90 EU6 PRIME SPORT TWINAMIC AUTO6 is a compact four-door city car aimed at easy urban motoring. Its small footprint helps with tight streets and parking, while rear doors and seating for four make it more practical than many two-door city cars. The Prime Sport version pairs a lively turbo petrol engine with a six-speed automatic, making stop-start commuting simple while keeping the ForFour nimble around town. It suits singles, couples, first-time buyers and small households needing a second car; it can manage occasional longer trips, though rivals with larger cabins may better serve regular family duties. mycarcheck.com recorded four checks across two VINs, so its figures are indicative, not a market picture: average private-sale value was £6,200, mileage 22,000 and annual use 6,000 miles; cars averaged three previous keepers. These modest mileages may appeal, but check each car’s history and condition.
