What is one of the best reasons for a Mazda5 (or any other type of hatch/wagon/spacevan)? Because it’s a portable paint booth! I spray painted a bunch of model parts in the back during lunch breaks at work. As a bonus, the windows allow sunlight in, which heats up the inside so the paint cures faster, and the interior is sealed pretty well, which keeps down contaminants, and I can crack the sunroof to let the fumes escape. Brilliant!
