Dealer service pricing anecdote
For my new-to-me 08 335i w/32k miles...
Oil change; brake fluid change; new spark plugs; software update; driveability inspection.
Dealer quote: $1,350
Top indy shop near me: $575, including OEM fluids and parts.
Guess where my baby is today?
[and yes, I would normally do all this myself, but I wanted the car worked over by the pros for its first service]
