Poor matches of Car and Caravan

We recently stayed at Buxton Club Site (Grin Low), whilst we were there an outfit arrived on site that alarmed usto say the least! it was a 2006 Mondeo 2.5 lire diesel estate,towing an Elddiss Super Scirocco. Subsequent enquiries when we got home confirmed that this caravan would have been 126% the wieght of the car. Which is a staggering, but not illegal match. I just hope I never run accross this outfit on the road, were I to do so I would certainly give it a wide berth! Has any other Members come accross a miss match quite as bad as this?
