When I bought LT5 gearbox fluid in 2011 for my first of 2 1Ms, it had an use-by date on the bottle of July 2016 or 5 years after manufacture. The brake fluid should be changed every two years. Coolant is 7 years old now. I would also buy a bottle of fuel system cleaner as fuel that sits in the tank a long time can also break down into gum and varnish. Fresh fuel helps break this stuff down too but can't hurt to throw a $12 bottle of BMW Techron fuel system cleaner.

Congrats on the new car.
Actually, per Mike Miller, the trans and diff fluids are changed based on miles only.

And while coolant is a good idea, BMW dealers are really hesitant - especially do to it right (and get it all flushed). But you should still do it.

Just don't waste your money on the trans and diff fluids.

And if you email Mike Miller, he will send you his lifetime maintenance schedule.
