Is the Z4 legally rated to tow a Caravan or Trailer?
I use my 325ti to tow the race BMW, it does a good job actually. Note this is the old piccie with nose weight too high and a boot full of spares and tools, I couldn't find the more recent photo?
I used to use my wifes Celica TRD Sports M to tow the race Caterham, that insulted one or two purists.
Both had a braked towing weight on the V5 though (1600kg on the Compact and 1200kg on the Celica).
