I've had mine for two years and just rolled over 40,000 with similar results. I'm happy with it, but want my Elio to extend it's life. It also helps to have a backup vehicle in case the Hybrid Batteries fail and I can't afford to replace them.We love our Prius. It's actually fun to drive (I worried it would be like a golf cart) and no matter how I drive it locally, fuel economy is near 50. Really, the only time it dips is hitting the highway and over 75-80mph. (always 40+)
It's been about 5 years and 100k, and all I've done is change oil, and replaced the smaller 12v battery. It's been very reliable and surprisingly comfortable and spacious.
