my 02 tl just hit 30k, yes i do not drive much with this car.

these are what i have done:
tranny fluid replaced
engine oil every 8k with Mobil1 synthetic
cabin air replaced
K&N air filter cleaned annually

what else needs to be done at 30k?

 

Sounds like you have it pretty well covered. Tire press. check and rotation?

Man,
I have 110,000 on mine, your 30,000 just blows me away.
