If I had to, I'd get another Prius. And I'd set it up just like the one I have now, including Brian's stiffening plate and spoiler, yoda's lightbulb antenna topper and Robin's leather trim. I'll probably be trading in when the new design comes out...2008 or 2009. Unless it's NOT a hatchback in which case I'll keep what I've got. My next interior will be gray. If they offer a nice, deep, dark blue exterior....
I'd consider trading in my '05 Package 1 on an '05 Package 6, and maybe I'd go with red paint this time. I may do an SKS upgrade in the future....
