You're right, beef. The California model does not have lean burn, due to tighter emissions laws in CA. The 49-state (or federal) VX has lean burn.
Welcome! I'm in WA also, and picked up a VX earlier this spring. I definitely recommend starting a gas log on this site, it helps you keep track of your mpg performance, and you can make notes as you make odifications along the way.
I was getting about 30mpg from my 02 VW Golf, but got kinda tired of its "nuances" and paid cash for a 15 year old, 179k mile, TEAL VX. And I really do love it. Great mpg, easy to work on, should last a while longer (and you can get low-mileage replacement engines pretty cheap, so I hear.)
