Interesting, I'm looking at my British Leyland handbook and it states a few things different to what you're suggesting:
Firstly the weight figures you give are different,... In my handbook the weight of a manual saloon is 640kg, and theTowing weight limit is quoted as 406.5kg
Rover not Leyland later cars like the one here are heavier however the important tow weights are nearly the same, dont forget these are max figures for braked trailers, the leyland book and the rover book tow figures are only 0.5% off each other so all years pretty much have the same capacity.
What does the leyland book say for nose weight?
This is about the only caravan type trailer thats light enough to tow with a mini thats available to buy:

still not braked so not sure if thats legal.
At the end of the day you dont want the tail wagging the dog so to speak
