My son is pleased with his new car, but he finds the ride a bit harsher than his previous 450e. He thinks the higher tire pressure from the factory is a contributing factor. While he wouldn't mind the extra horsepower, he values range and a comfortable ride more, especially since he mostly uses the car for short trips with his girlfriend. That said, it still has plenty of pep for everyday driving.
The rear seats fold down almost completely flat, which came in handy during his recent Ikea run. He was able to fit some bulky boxes in the trunk without any problems, even with the slight slope where the seats fold. He do think the RX might offer slightly more cargo space overall
