So took the car to the first show since Wekfest 2019 - reaction was super positive and people were doing double takes on the highway!
Overall very happy with this project as it's given my M3 a ton more space, we were able to load 2 canopies, chairs, tents plus all my usual car show gear and still RETAIN my back seats for the kiddies!
The box does create some wind noise and probably affects the MPG but I won't be keeping it up there except for shows.
My favorite view is the back side jet thrusters
