Scott,
We are looking at a 2008 BMW 335i, v6 turbo with 94k miles for my 18 yr old daughter. Asking $10k, is that a reliable car? Any major maintenance due at 100k miles? Should we buy it? Thanks in advance.

Don't buy it. Any modern BMW after 100k miles is a foreshadow of an endless money pit.

Please consider something slower.
v6 turbo
I'm going to assume you meant the inline 6 turbo.
The main concern with this is that they burn tons of oil, and have the rat's nest called VANOS.
It's not a cheap car to maintain - it can get 'real expensive real fast'.
Should we buy it?
I would not, sounds like a deathtrap for an inexperienced driver.
These also can cost a fortune to fix, depends mostly on luck with these piles of junk.
EDIT: BMW did offer the “Drivelogic” transmission on these, a wet dual clutch - it’s a pile of trash, to be avoided!
The other transmission a 6 speed auto is decent.

Reliable, yes. Expensive to maintain, yes. If you don’t maintain it, it won’t be reliable. It’s still a money pit.
