I plan on tossing one of my winter tires in the trunk. I prefer the round foam that holds the jack to the nice bag Dackel has. I'll put the foam inside the winter wheel and the whole setup inside a discount tire plastic bag that's inside a tire tote, and viola, only 80% of the trunk is gone instead of 90%
The question is; will the jack from an E60 work on our cars? They are all over the web used, and probably in the local junk yard.
The answer is yes. The kit Dackel has fits many BMWs. Here is the list
