Buying Tips for the 2006 BMW 3 Series (E90/E91/E92/E93)

  • ✓Budget for suspension, brake pipe, and water-pump work on cars still wearing old run-flats or original arms
  • ✓If it is a 320d or 318d, demand chain-proof paperwork rather than trusting a quiet engine on the day
  • ✓Check every exterior light, window, and mirror because FRM and wiring faults are common on ageing cars
  • ✓E93 convertibles need a full roof cycle and a dry boot floor before you think about cosmetics or spec
