Talking about my past Lexus models, I started with a 2008 GS450h, and… WOW, what a car. So, when I traded it for a full spec 2014 GS300h I found it "better" almost in all features, except for power (from 345 to 220 HP): it was more than sufficient for normal driving but I missed the V6 performance of 450h. Meanwhile, I had the chance to try NX 300h and I found GS 300h superior in all, so, when I decided to try a SUV it could not be a NX, I got a RX 450h. Not fast like GS450h but quite a fast SUV, I am not worried about passing with a 0-100 km/h of 7.7 s, and an excellent ride and comfort. May be the SUV for you, coming from that cars you had experienced, is RX 450h.
