Oldest tow car?

Do I have the oldest tow car on here? I have a 1972 Land Rover series 3. Ok it isn't my every trip tow car but for local trips out we have used it and it tows the 2011 Unicorn Valencia very well. Only down side is the spare wheel has to be taken off the boot to get the alko handle up vertical to hook the van on! For a 40 year old petrol engine it does the job amazingly well! I haven't braved a motorway yet though!
