It's over 175,000 miles, and never once had mechanical problem. Replaced thermostat at 165K, and other than routine maintenance (wear/tear), transmission and engine is in excellent condition. My friend didn't believe it is over 175k because the engine is so quiet. Commuted between Vegas and LA last year every weekend, and never broke down in the desert. Gets 36 mpg, why pay more for hybrid. This one is a keeper. Great for one or two person drive around town doing chors. Space and power is limited, but we didn't buy it for those. We have a 4Runner and Sienna for those. We only drive Toyotas because of their quality.
