I recently acquired my parent's 1985 Peugeot 505 wagon (North American Spec) and have been working on getting it road worthy. The cargo area is roughly 7 1/2" by 3' with the rear seats folded down and you can throw over 1000lbs of crap in it (according to the owners manual), not to mention it is RWD with a live axle, semi trailing arm/coil spring rear suspension, and a limited slip diff. It also floats over bumps in the road unlike my W250
The drawback is being a passenger car based vehicle, there might not be the clearance needed for some console TVs
