my dealership said it's time for the 30K maintenance. It seems rather expensive to top off the fulids.
Is the 30,000 mile maintenance essential on 2008 Lincoln MKZ
According to the estimator link at the repairpal home page it is a new cabin air filter, oil change with filter and lube, lots of inspections to make sure no problems are coming up, and at times the schedule could be bumped up depending on what conditions you operate the vehicle. You do not have to do maintenance with the dealer. Another qualified shop can do it. Can save some money that way. The main thing is that you keep documentation of it in case of any warranty claims. If you are going to keep the vehicle then recommend it but is your call.
Make sure the pricing for the service you are offered is in line with the service you need. Like Ron said, oil and filter change, tire rotation, engine air filter, cabin air filter and multi point inspection is all that is needed at 30,000 miles. Many shops will add fluid exchange services and other "premium" add ons, but sticking with the factory minimum...I would think the price should be maybe $180 - $200 or so for the services needed?
