Buying Tips for 2014 Smart Fortwo (453)

  • ✓On Twinamic (dual-clutch) models, check for smooth take-off from a standstill; hesitation can indicate clutch wear or require a software update.
  • ✓Test the exceptionally tight turning circle to ensure the steering rack operates smoothly without clunking at full lock.
  • ✓Inspect the front suspension over speed bumps; the short wheelbase means bushes take a beating and can knock.
  • ✓Check the infotainment system (Media-System) for responsiveness, as it can be laggy and prone to Bluetooth drops.
  • ✓Verify that the bonnet (which slides forward rather than opening upwards) is secured properly and the locking toggles aren't broken.
  • ✓Look for signs of water ingress around the doors, as the frameless windows can sometimes struggle to seal perfectly.
