just like pyramid said, make sure to get an out-of california model VX. I learned this when searching for my vx. the epa estimates really arent that different, but the real-life mpg does differ between the two.
i "may" be putting mine up for sale sometime soon. ive been toying with the idea of getting a tdi.
im in socal btw, and i think im one of very few with a "lean burn" vx in california
