Now that my 2004 Prius has over 220,000 miles on it, I consider it "nicely broken in". 4 times this month, I went over 700 miles on a single tank of gas. I deliver car parts in it for a living, and the company I work for (WorldPac), is replacing all of their Toyota Tacoma trucks with Priuses. I just put 110,000 miles on my 90,000-mile Michelin tires which I keep at 44 psi. Still have the original brakes. It takes a while to master techniques to get over 60 mpg on the highway, but I think I've got it down now.

Congrats! If you haven't already, you should add your post to http://priuschat.com/forums/gen-ii-p...mile-club.html.
