I Wish I'd read this post a couple of days ago.... I rented a trailer yesterday to tow the caterham (s3) to a track day - talked to two trailer dealers, told them the car (VW golf), they told me the max towing weight was 1400Kg and because their trailers weighed less than 3/4 tonne I was fine to tow - clearly this isn't the case as the trailer gross weight was around 2000Kg... That said, I loaded the trailer properly and the golf did brilliantly, even when a lorry decided it wanted my lane whilst I was along side! That manouver in my old defender would have resulted in a lot more drama...even without a trailer! But if that's what the law states, then I'll have to find a company that rents trailers with a GW less than 1400Kg, suspect I'll be out of luck. Glad I wasn't stopped. Tom
