Ask First
If you have a reputable dealer, they will be able to give you a quote over the phone. I asked in advance for my 10 hour price and it was $50 higher when I picked it up. They said that the quote was for the labor, not parts. Buyer beware. It reminded me of that commercial on TV where one girls gets a toy pony and the other gets a real one, The Gipped girls said " I didn't know you could get a real pony" and the announcer said, "You didn't ask".
Now I always ask for the total price, parts and labor out the door. Mine was Just over $300 for the 10 hour service on an 08 Challenger 180 215 at my local dealer.
The break-in was worth it though as my Challenger really flys now. It is way too much fun!
