Sorry should have said Z3 not Z4. I would tell my insurers who, being NFU, have always been understanding and accommodating. No not the eye but a tow hitch for a trailer. I have seen them in the past and I know (think) they are limited to 500 kilos towing capacity but, the Z3 is my only transport these days and I need the practicability a small trailer would give me from time to time. Otherwise, the Z has to go and be replaced which I dont want to do. I sold my immaculate low mileage E36 318 ti to pay off my divorce legal bill!!! The value of the Z3 wouldn't have covered it so the sacrificial choice was made for me.
