Well, I'm at 293,000 miles and it just keeps going and going. This is my second Mazda and Father bought a couple about the same years and always run up to and above 200k. I used to haul papers with it (sometimes thousands of pounds) and it was always reliable.
Very reliable and good on gas. I recommend the cab plus for the extra leg room.
Won't win any drag race but will keep up with traffic. U-joint is sealed, so if the U-joint goes bad (and they do at about 100k) you will have to replace the entire drive shaft (couple hundred bucks).
