I just picked up my GS 450h last week and can already say that I love the car. The performance is amazing and I give Lexus high marks for the quality of the car. I traded in a 2002 GS 430, which I was extremely happy with, but this car has it beat in every category. This is the most fun I've had driving a car.
I ordered mine in early aug. I picked it up 3 days ago and it is a dream! I do have a few issues though. As a tall man, the entry is a headbanger! That's why I gave it a 9. As a heavy man, the center console is not sturdy enough. Also Hi-octane gasoline is an economical nightmare in Tokyo. That's why the 7. I don't need to drive so fast anymore(did that with my Supercoupe)! Can't fit in the Prius. But all things considered, I am super satisfied with it. I plan to keep it about 5 yrs, and I am now confident that I will have no mechanical issues. I have owned and driven many autos, American, Japanese, German, but this is the best so far. I'm also happy to be the first to own one.
This is one of the best performance cars in existence, BUT I bought it for the mileage it says you get and it doesn't come anywhere near what it is supposed to do. If you want a performance car and don't care about the validity of the hybrid performance then it is an exceptional vehicle. My goal was to have a true hybrid. I am very disappointed.
Excellent quality but does not fee like a performance car as compared to a BMW which I traded in. Feels good to be driving a hybrid there is slight hesitation when accelerating---not yet sure if it is due to engine shifting or something else
