Well, that's good. I'd be very irritated if a car lasted less than that.
My 1998 Durango lasted 235K miles and was still fine when I donated it and didn't have many problems in that timeframe. It was the first year of a Durango. I've had other American branded cars and kept all of them to over 100K miles. Although my primary vehicle is now the MDX, a Japanese brand made in the USA, I'd have no issue buying another American brand vehicle. I wouldn't buy based on gross generalizations of the manufacturer native country, especially when many of them, including Lexus, assemble the vehicles and source subcomponents globally.
