I had done the research as part of my buyers guide,
and now made a sticky as requested (Dragrad)
Both the 75/75 Tourer and MG ZT/ZT-T dont have any additional towing weight differences, so a saloon can tow the same as a tourer. It should be noted that the LWB/LIMO cars are lsited at the bottom after considerable searching.
HOWEVER the engines make a massive difference to the towing weight and such, so please folks, keep your selves legal and your cars undamaged.
It should be noted the towing weights are as follows (these include the trailer you are towing and load, and not the load seperate as many people discover!)
Please note the KERB WEIGHT and 85% KERB WEIGHT are typical of the cars accross the Rover 75 and MG ZT range, and that they can vary as much as 50 kg depending on your spec, so this is an approx guide based on Rover information from several owners manuals.
