We replaced our 03 GS300 with an 06. Loved the old one figured we'd love the newer one. Wrong. Brakes, cruise ride , AC and Nav don't work as good as old car. Ride and handling choppier also. Tranny hunts for gears at low speed and in the hills. Has been in the shop 5 times in three months. Disappointing car. Great to look at but no fun to drive. Am going to trade for something that I can live with.
Looks. Gas mileage. Stereo. Acceleration. Turning radius.
Try improving on the previous generation car. Holy cow! I thought I was upgrading. Brakes are awful. Kids and wife constantly complaining about my driving in this car. Cruise control is spastic. Constantly hunting gears and racing engine. I love the old GS but can't wait to get rid of this one.
