This. The 450h in my area was 10K off and only was a few Ks off the F-sport. I didn't like its CVT though. If you're thinking of the 450h, I would recommend checking out the regular 350 Fsport. You do get ~10mpg more on the hybrid, but the driving characteristics aren't that far apart, and may even be worse if you don't like the CVT.I would get a Q50 Hybrid, but that's because I really don't like the design of Lexus' hybrid. It's powertrain looks indirect, has two, isolated planetary gear transmissions, two motors (one of which only charges the battery and starts the engine), and the car is actually a tick slower than the GS350 F Sport despite having a little more horsepower and what I assume would be a higher torque rating. If it's going to wear a 450 badge then it should have noticeably better performance than a 350, not worse. That being said all anyone can do on here is share their opinions for your consideration. Ultimately you have to pick what you really want. I'm lucky in that the Q50S Hybrid fits me almost like a glove in having what is important to me in a car, but there are some people who downright hate the Q50.
Of course i was thinking about GSI assume you mean the GS450h, not the RX450h (SUV).
The Q50 Hybrid is sold as a Skyline Hybrid in Japan while the G37 is sold as the Skyline. I imagine they will eventually begin selling the 3.7 Q50 as a Skyline and stop selling the G37 at some point. Who knows. I lived there so I know Japan/Japanese companies can do some weird things. I don't know why they never came out with Acura, Infiniti, and Lexus initially there like they did everywhere else. It would have saved them some headache that Nissan is going through now trying to sell Infiniti badged "Nissan Skylines" in Nissan dealerships to save on creating a whole new Infiniti distribution system. That being said, I do like that some of the cabs in Tokyo are Q70/Nissan Fugas. Very klassy.I wouldn't brag on the GS450h's back seat room. The Q50 may actually have it beat here. My GS350 (same model, diff drivetrain) with me in it might fit a small kid behind me but that's about it. I'm 6' 7" and don't even have the seat fully pushed back, but that back knee room is tight. Due to the roofline, the trunk gets priority over rear passenger space. It does have a VERY usable trunk though. It's wide and deep but I miss Infiniti's "hidden arms" for the trunk lid. The GS's trunk lid arms intrude into the trunk space.
Now the LS on the other hand...it's practically a limo in comparison, but it's also a much larger car and waaaayyy more expensive.
Ultimately, back seats and trunks aside, I'd say the cars have two completely different personalities. The GS450h won't be nearly as sporty as the Q50h. Remember, the Q50h is marketed as a sport hybrid, and the torque punch off the line is worth it. Final word, Infiniti only badges the Q50h as a Skyline in Japan. None of the other Q50 models get that designation.
If you want a gas sipping reliable car, both fit. If you want more of a highway cruiser than a canyon carver, go for the Lexus. If back seats are for decoration and as long as the trunk fits a few golf clubs you're happy, get the Q50h. You really can't go wrong with either one, just be honest with your intent before you go drive them.
When I went it seemed most Taxis were Toyota Crown's until I got to Yokohoma...then I noticed tons of Fuga taxis.couldn't figure it out until I drove past the Nissan H.Q..very nice building and locationThe Q50 Hybrid is sold as a Skyline Hybrid in Japan while the G37 is sold as the Skyline.

Don't get any ideasInteresting that they charge more for metallic paint in Australia.
