Very good car — responsive, supple, comfortable and reasonably economical. Not quite at the German premium level for noise insulation, but very close... Exceptional chassis.

As a Rafale owner, I'm happy with my choice. The car is spacious, feels luxurious, quiet, robust and very efficient at the same time. I also feel more “up to date” compared to the RAV4.
