I bought the box for my Einser BMW Transport my pug. The box is made of the same materials as the boxes of 4pets which 3 are however times more expensive. They fit the millimeter precision in the trunk (for me it is far left, so I left nor may invite other things (a weekend getaway for me and my wife going to slack off). But you have the box increase about 15 cm (rear slightly lower) to bring to the door on the loading edge. For the price there's no better box, and custom-made is not necessarily !!! Assembling the way alone in not quite 30 minutes.
