Could you please let me know what is the average cost of 105k service...
Also please advice whether should I have it done at the dealer or perhaps could it be bone at so e different place?
I stopped at the shop and the mechanic said he could do it for around $800-1000. However they have not dealt with Nissan Murano before. He said he could do it... What's your advice?
Thanks for any input.
There is no need to take your MO to the dealer for any non-warranty work. Any competent mechanic can handle the tasks.
The only special item called out at 105,000 miles is the spark plugs. Nissan recommends they be replaced at 105K. The front plugs are relatively easy, however the rear three will require some work. Check out this thread: Spark Plug Replacement (how-to)
All other items (oil & filter, engine air filter, cabin air filter, belts, coolant) follow their normal replacement interval.
