I just drove it on the California Speedway today during the Lexus Driving Academy event...and I have to say....its MUCH MUCH better than I thought (probably because I was so disappointed with the IS 350).....the only thing that I do not like was the steering feel and the exhaust...and the engine is kinda lazy on Auto mode....but once in manual.....its pretty powerful!!!
Wish I can spend more time with it on the track...
