I was thinking in what would be the best thing to buy in order to keep the grocery bags in place (inside the trunk).
BMW offers some options.
For example, the grocery gripper, but I don't know how much this things can handle and seems that I will need to drill that part of the car.
(also, is listed in the 3 series part, not in the M3, so maybe it's not compatible.. I really don't know the car yet).
The other option is the collapsable bag, which seems to be pretty nice.
Another possibility is the trunk floor net.
Does the M3 come with the hooks for the net?
Any experience with this stuff?
