Buying Tips for the 2008 Volvo S40 (P1)

  • ✓Powershift cars need documented fluid servicing; without it, jerky low-speed behaviour usually means future expense
  • ✓Diesels should be checked for EGR and DPF health, especially if the car has spent its life doing local school-run mileage
  • ✓Door locks, window regulators and other cabin electrics deserve a full test because small faults are common and rarely come alone
  • ✓A straight, quiet manual 1.8 or 2.0 petrol often makes more sense than a cheap diesel with warning lights recently cleared
