Buying Tips for 2001 Volvo S40 (Gen 1)

  • ✓Check rear arches, sills and the lower edges of the rear doors carefully because corrosion repair can easily outweigh the value of the car
  • ✓ABS lights or a dead speedometer are rarely trivial; module repair is common and should be priced into any deal
  • ✓A quiet front end matters on these saloons because tired bushes and top mounts quickly make the car feel loose and neglected
  • ✓The best buys are usually unmodified 1.8 or 2.0 petrols with long-term service history rather than bargain T4s with patchy paperwork
