My Kodiaq 190 DSG 7 seater, came with the electric tow bar fitted, I use the vehicle to pull the caravan. Also it came with biscuit spare wheel, which is no good, if you are towing, if you have a flat, the biscuit is not legal.So I bought a full size wheel as the spare, it is to big to fit in the spare well, because of the mechanism for the tow ball. I have to carry it in the boot , and takes quite a bit of room up.
Prier to the Kodiaq, I had a Superb, which I may go back to, in a couple of years. However with that, I had the tow bar fitted after purchase, with that I also bought a full size spare wheel, which did fit into the spare well, maybe the same would apply to the Kodiaq. But I think the Kodiaq is a great motor, as yet no probs what so ever, July 2 years old, as yet covered 7500 miles.
