The problem with Skodas and towing is that there are very few Skodas on the road yet compared to other brands and most of the local third party tow bar manufacturers don't have kits available so owners are forced to buy factory fitted (as in when the car is assembled in CZ) towbars and wiring in most cases.
Over time the third party people will develop local kits but at the moment there ara very few if any options for most people.
