I have had no "rattle and squeaks". Actually the body and interior feels unbelievable solid. I have driven the worst highway ever on Poland and there was no noise from the interior. I was amazed.

You could drive max 60km/h. All those seams were at least 10cm higher than road between the seams. So it was like driving on an sharply frozen windy ocean. Really really awful, do not use that road ever.
During normal driving, the only rattles come from dash, as the climate control changes its flap positions.
The only thing I am not sure is how your dogs would fit into the boot. Test drive?
