The prior series Tundra was just named as one of the top 10 worst used cars a person can buy.
Not sure where you are finding that. In the April, 2009 issue of Consumer Reports the Tundra is listed in the "other good choices" when talking about used trucks. April, 2004 Consumer Reports Satisfaction Survey lists the Tundra as "most satisfying".
I have an '06 SR5 V-8 that I bought new in August of 2006. It now has close to 190,000 miles on it and drives like the day I took it off the lot. One of the most fantastic vehicles I've ever owned, totally reliable and dependable, comfortable and quiet. It also goes like heck with the 271 hp V-8. I really don't know if this truck will ever wear out.
