Hey guys,

My wife's 2007 X5 is now reaching 110,000 miles and I wanted her to take her car in for some preventive maintenance. The service technician recommends the following:

transfer case fluid
differential fluid
spark plugs
air filter
transmission fluid


Probably will cost me a little over $1000 for this work. Is this something you think I should do? I've been reading a lot of conflicting opinions on the tranny fluid. I'm thinking that I should just go ahead with it.



Is there some other work I should get done?


What do you guys think?

Thanks!
