I have an old but serviceable trailer which I have advertised on Gumtree https://www.gumtree.com/p/other-vehicles/car-transporter-trailer-single-axle-1300kg-gross-winch-spare-wheel/1168181343
here.
Just in case anyone is looking for a 1300kg trailer that is not wide enough for a Haynes Roadster or a Spire (1.56m). Photos and full details on Gumtree
