Im at 15k and I have to decide weather to pay for the 15k service package or just do oil/filters and tire rotation. Looks like the rest of the service is mostly inspection of stuff that should fine at 15k. I live in Columbus, Oh and Nissan priced the 15k service at $335 and Infiniti was $429. Any thoughts on the value of 15k service or pricing would be helpful.

Only thing you are really paying for is to have a service record/warranty.
Other then that. i think it's all bs.

Dont bother with the 15k service now once you hit 30k you will want to have it done

Yep, its just for the paper trail if you ever sell the car you can prove the services were done.
