I'm glad you had the option, Dave. No towing/trailering outfit over
here in the US would touch my BMW, and the dealer flatly stated "you
can't tow trailers with a BMW". So I was on my own - absolutely no
choice!

By the way, equipping the BMW to tow the Cobra was easy. It took 2
hours once I had the Kriss isolator (the only isolator made, AFAIK,
that isolates independent cars and feeds independent trailers). The
real challenge lay in getting the Hoppy 48845 (needed to drive a
combined trailer off of the Kriss) to work properly! Hoppy engineers
said they had never heard of anyone doing it before - and all it needed
were simple 470 ohm 1/4 watt resistors.

Does sound very complicated and time consuming. What
I did was contact a local (Sheffield, UK) towbar company
who came and fitted one to my BMW at home for about
£250 towbar, electrics and fitting, and it works just
fine on my Cobra.
