Seems like if Crimsonsky wanted to use a G-wagon, if she paired it with something like QOS' Brenderup trailer, she'd be a happy camper.
Here's from a US Brenderup website stating you can haul them with your usual car.: http://www.theydeservethebest.com/brenderup/towing.html
Last year I was looking at getting horse trailer, and my husband cringed, because "then we'll have to get a new truck too!". And I told him I was just planning on using my Outback - I'd seen it done many times. He looked at me like I'd grown 3 heads. I'm starting to get it now. The US trailers seem to be designed in a way that requires much more... oomph.
