I thought of this thread the other day when this thought occured to me:
"The seat warmers in my Lexus just get to darn hot!"
(Background: I bought a Lexus ES 300h hybrid: 6 years old, 90,000 miles. It should last a long time, it's really comfortable, and it gets more than 40 MPG. It was little bit - ok, a few thousand - more than a similar vintage Camry Hybrid, but a whole lot nicer. Except for those damn seat heaters... You may begin your sneering judgement now.)
