1:400 BMW Series 3 set of 15 for your 1:400 airport. Even though there is no tabs, make sure to glue the inside so you can roll the chassis and top of the vehicle. It also makes it very sturdy and balanced if you add an infill inside of it.
It is very intricate and small, but if you have small hands you can make it :D Just screenshot it and make sure to increase the size by 35.57% if you are in full screen. (It is ultra complicated) I will add a preview of how it looks as a complete car.
