The way I'm going, tires are going to be more than maintenance.
@dpcompt, have you considered the pre-paid maintenance plan? I acquired it before my first service and received a PCA discount. Plus, I didn't have to pay sales tax (6.75% here in NC). Whereas, if I purchased each service at the dealer, I'd pay the cost plus sales tax. For four years, I just need to drop off the car for the annual service and sign with no payment.
After the car is out of warranty and expiration of my 48 month pre-paid plan, I'll likely be using a highly recommended independent shop and doing more of the work myself.
FWIW, the non discounted cost of the 4 year service plan was $3,200. So, I would expect around $800 / year on average to keep the car on the road maintained by the dealer.
