I used to think the same thing, but recent experiences tells me otherwise.
The last three cars I have sold:
2008 Audi TT - non-dealer services, 12 monthly
2009 Audi S3 - non-dealer services, 12 monthly
2008 Prado - full dealer service, 6 monthly (as per Toyota spec)
The TT and S3, they just checked that the services had been done. The Prado he didn't even look at the service book. Told him it was full dealer service, he was happy. Not once has the service history come into question.
All my cars are low klms and very tidy, so I guess they just assume all is in order. My LR4 won't see 100K during my ownership, so I guess the same again will apply.
I think it comes down to how your presents and drives.
Cheers
Dan
