We purchased our burgundy Tundra Double Cab Limited 2WD new...had all options:
sunroof, leather, 6-disc in-dash changer and dealer installed Borla exhaust (which sounded great--it was the wife's truck and she wanted a truck that sounded like a truck). Our Tundra performed wonderfully but we sold it when gas prices shot over $4/gal because it really was only being used as a commuter-got about 16 in town and could squeeze out 20 on the highway.
As a boutique truck it did great--smooth ride, 5 adults could travel in comfort and the full size bed w/ tonneau cover could carry ridiculous amounts of luggage.
The only real gripe was the "old school" looking dash board.
The transmission tended to down-shift too easily when cruising on the interstate going up a hill--the computer's programming was probably set up under the assumption the truck would be hauling more weight than we did.
Also, this was probably more noticeable since we had the Borla exhaust on it which really could not be heard when cruising except when the truck downshifted.
With the stock exhaust I would assume the downshifting would be less noticeable.
