fsx, this is Escalade EXT. The long bed in the back is how EXT models are. This limo was most probably imported form the US. It seats at least 18 passengers. In the US, the bottom part of the front passenger seat is usually removed to accommodate additional entertainment electronics and cooling unit. If someone had the photo of the back of this limo, you could see the emblem of the conversion company that did the work and visit their website to obtain more information.
