Buying Tips for 2007 Vauxhall Astra H

  • ✓Any 6-speed manual needs an M32 whine check in 5th and 6th and a look for gear lever movement under load
  • ✓CIM and steering-column faults can generate confusing electrical symptoms, so check lights, horn and wheel controls carefully
  • ✓1.9 CDTi diesels can be great mile-eaters if maintained, but swirl flaps, EGR and DPF neglect quickly spoil the bargain
  • ✓Astra H suspension is usually cheap to fix, but repeat rear spring and front-link advisories show a car that has been run on the cheap
