Hi, I am from Australia. I also need to buy Tonneau cover, because I used to cover my Z4 with king sized bed sheet lol, but in rainy season there is a problem to cover my car.
Often wondered why modern cars dont come with a Tonneau so you can drive solo and keep the heat in annd stop your stuff blowing about.
Standard on old school convertibles - good for parking too to stop the dippers ( thieves) but I guess electric hoods outpaced Tonneaus.
Seems some "Tonneaus" are actually car covers not compatible with being driven.
If you finds one - please post so we can all benefit. good luck
I have had a tonneau cover on old Escorts to cover the hood and also a full tonneau to protect the cabin when the roof is down and its sunny out - they did exist on older vehicles but never seen them for a Z4
