After printing it out ages ago I finally knuckled down and painted another vehicle from Digital Taxidermy, namely their "Omni-truck public service vehicle MK1". Even with a not-that-well-dialed-in 3D PLA print it's still turned out nicely.
It's a great big recycling truck for the more "meatier" waste of the future city. It'll do a great job blocking line of site for those cross street dashes!
