I was quoted by a local Infiniti dealer here a price of $330 for the 45K service. They'll deduct for oil change, wipers, and tire rotation when I get there, they say, since I did those myself already, so I'm guessing it'll be down to about $280-290. Does that sound about right with what everyone else pays for this service?

i used to work at a dealership and the usually charge about $80-$100 an hour which is crazy but yea that sounds about right ....

what else left for 45K????

!!!NOTHING!!!

exept maybe a cabine micro filter
which you can DIY for 10min.

Yep--and a bunch of inspections. I'm not yet comfortable with taking the dash apart myself yet to change the cabin filter...

you dont have to take the dash to change cabin filter
you just have to take lover glove compartment out which is taks about 2-3 min

More like 10-15 minutes to complete the job.

At Nissan a 45K was oil change, tire rotate and balance, wipers, air filter, additives, and clean and service the brakes. They charged $250 for that if I'm not mistaken. It paid 2hrs in labor but I could bang it out in about an hour.

just take it to some privet shop and it will cost you 20-50% less
UNLESS you have this life time power trane worranty (which my dealer offers) with only one agreement you have to do every oil change and service at the dealer only.

Nope--just standard warranties. Anyway, I'm ordering brakes to do a complete brake job, changed oil, recently put on snow tires and changed wipers, so there isn't anything left for them to do--except the cabin filter. I think I'll pass on it...

The filter job is easy, only 5-6 screws and then swap the filter.

15 minutes.
