I have an IKEA LAIVA desk for sale. It's wonderful for small spaces or if you want to have a designated small desk for certain tasks. The desk is in great condition, but if you look at the second picture in the link below, you will see that the power strip is resting in a nook in the desk. I don't have the boards for filling the bottom of the nook, but currently have cutout cardboard pieces in place that serve the same function and work perfectly: http://www.ikea.com/us/en/catalog/products/70176519/

The desk is assembled and should fit into the backseat of a four seater. If you have the IKEA Allen wrench, you could disassemble it for transport.
