I think that is probably true about Nissan Pathfinder buyers/owners, though I wonder why that is.
I probably fall more into that category than not. I've had generally good experiences with the dealer, though I have wondered if I have paid too much. In the grand scheme of maintenance, it has come to less than $50 a month, but with larger services left to come, this amount is subject to increase. In the past, after having routine services at a local shop, I was left with a rattle in my exhaust system and the bottom cover of my vehicle not fully secured; so I ended up taking the car to a dealer who knew my car to get this fixed. If what you say is true, and even a new buyer would likely not be that mechanical, it seems probably best off just getting it done with the dealer who I feel comfortable with.
