Dealer Maintenance Packages

Hey all. I've done a few searches and read a few threads on this so forgive me if this is a well worn subject.

Basically, here's the deal. My 2005 Prius is at 120,000 miles. I have taken it into the dealer every 5000 miles and always had whatever recommended package and maintenance they suggested. This was the first new car I ever owned and I wanted to make sure it was as well maintained as possible. And especially when I bought it, Priuses weren't as widespread so I wanted to make sure I took it to someone who knew the car and what to maintain and check.

Now today I just dropped $500 on the 120,000 mile maintenance package and an engine cleaning to get rid of carbon buildup around the intake valves (or something like that). Ouch. Am I a good car owner just making sure my investment lasts as long as possible or a shmuck with no car knowledge getting milked for way more money than I need to be? Are there any places where I can see something like "get A done, but you can pass on B and C"?

Thanks for any input and opinions!

 

I just meant a generic A, B, C like "oh at this mileage you just need the oil and filters changed but you can pass up the other recommended stuff as it's not needed." I've just always taken the better safe than sorry option.

 

I knew I'd feel like an idiot at some point. That point has arrived! Thanks!
