I'm looking to buy a good used XD or similar for my duaghter. I have an XB1 and couldn't be happier with it. Is there much difference between the XB1 and XD interior size? I really like roominess of the XB1 interior .

 

The xD is actually quite similar with the interior. It is open and larger than you'd think compared to the xB. I think the xB might be just a hair bigger, but the xD is definitely roomy like the xB.
