Not really. Most of the time, they do basic servicing during the warranty period. As once most cars are outside that, people simply dont use dealers as they charge too much. So they dont have a wealth of experience of problems that do occur in older cars.

And you just need to see some cars that have just left the dealer network with full service histories coming in for their next service.

Ive seen loads that have never seen an air filter before, pollen filter. Hell, some you'd be sure the fuel filter has never been touched, or spark plugs etc
Many dealerships, for whatever reason, dont even carry out the basic tasks they are supposed to, but sure as hell charge for them !
