how to celebrate?

Just passed 100k miles today what do you guys think I should do to celebrate?

Should I buy her something? If so, then what should I get?

I need ideas!

A cam? Sorry, I could not resist. How about a nice wash, wax & detail? And of course, a couple of beers for you.

A tune!!!

Well I'm working with Keith at green Diesel Engineering so I've got a tune
And a fun note, I've owned the car since 83k miles about four months ago and it has saved me 680$ a month in fuel costs and about 3400$ in fuel since I bought it. This is from switching from a 1995 pathfinder that got 15mpg.
Things I plan on doing are a timing belt(obviously), Audi r8 style projector headlights, a 6 speed swap from my 5 speed, awd Conversion at around 200k miles, and maybe some sort of euro taillight.
Any other ideas for my car?
