Replaced front tires at 46,000 miles.
I'm completely smitten with this great little car. It is built rock solid yet it is quick off the line. The seats provide excellent support and the overall impression of the interior materials and their fit and finish is that of a much more expensive automobile. The handling is agile and responsive and even when cornering at great speed the car remains flat. All this with 50 + mpg! These are becoming highly collectible, but I plan to hold on to mine!
Don't know how you are getting 50+ mpg with yours -- best I ever got on my '99 was 34 mpg.
Better look at getting your timing belt replaced soon -- if it breaks while the car is running, your engine is toast.
