As said not a common problem if regular maintenance and the like, probably blocked oil feed line. GCG do good work so they should have it all running well now. Yes redbook is wrong but fee free to haggle. I wouldn't be paying more than $18k for an 08 with 100,000kms. If you can't find one that cheap in good enough condition wait a bit longer. I paid $20k for an 08 2 years ago with 78,000 and it had tech pack and sunroof.
