Hello scorpius
From data bases ( which could be wrong) then BMX has
Gross Vehicle Mass of 1915kg
Max towed mass 1600kg
That gives a theoretical GTW 3515kg Which if you caravan was MTPLM or MAM 1600 would exceed the post 1997 standard driving licence limits of combined MAM of 3500kg.
However if your towing ratio is only 80% then you will be well within this limitation.
In terms of performance the outfit should be plenty powerful enough, though early BMW's did have a reputation for being difficult in slippy conditions. This could be down to drivers not being used to rear wheel drive cars.
