This was my fifth one in the series ... they are all terrific "flat-pack" models. I do all the edging in Sharpie, which is a little tedious, but they come out looking fantastic. The only horrible parts are the bendable panels, in particular around the engine compartment. I suspect those all depend on what the weather was like when the laser cut them out. The roller panels were a breeze, and there are spare parts galore.
