I can tell you that in my area without any problems just a normal service has cost me the following:
Inspection 2 was $2320.00 (Includes Inspection 1 plus minor service)
Inspection 1 was $1050
Minor Service $780
These were the highest prices I paid.. I thought the dealerships would all be charging the same but this is not the case... found a dealership to do my minor service for $395!
Best thing to do is call around your local dealerships and get prices on all three types.
If you can buy one with a service warranty then do it... these puppies are NOT cheap to repair.. trust me on that
good luck
