I've owned a '95 SC400, '01 GS300 and just recently picked up a 2005 ES with 42k miles. I did notice a small hiccup in the transmission when accelerating slowly from 35 to 40mph, but when you accelerate faster you don't notice it. I'm not sure if it's even worth going to the dealer to fix... other than that SMALL thing I really like the car and am looking forward to my next 4 hour drive. This is the smoothest car I've ever driven, and for the price (19K) I feel like I've gotten a very nice car without a very high price. When I drive this thing I feel successful!!
