Hey Daniel...
The only one I've seen is the flatbed that one other listed below... they are indeed a kick in the butt to use and simple... but also heavy and expensive NEW. Usually sell for about 2500 used.
The Aussie one you posted is indeed something I've seen before in Australia... but nowhere else... and looks MORE appropriate for hauling a 2000 lb X, but nuttin' else.
I'm unsure WHY you want the trailer but if you plan on hauling any REAL cars, the Aussie trailer would not be sufficient. Secondly, I find FLAT TOWING my X to be relatively convenient without the hassle of a trailer, the only limitation is the inability to BACK UP. I've towed mine several thousand miles without a "hitch" as it were, and the cost was about $120 for the lights, tow-bar, and materials to build an adapter. More info if ya want...
Keep yur butt down!
