If it’s molded in the color, I’d definitely prefer a kit option for painting before assembly. How hard is it to get the tires off and windows for painting?
As of now the only pieces planned to be permanently attached are the turret windows, which will be glued in place. Body pieces and seats will come assembled, and are held together with screws. Everything else (doors, gun, antennae, windows, mirrors, tires and wheels) will be snap fit pieces. Overall it should be an easy disassembly process.
Regarding disassembled "kit-style" vehicles as well as offering separate pieces (I've been asked about it elsewhere), it's not in the plans right now. Initially the plan is to keep the offerings pretty streamlined thru Kickstarter: Desert Tan MARV base goal, likely 2-4 variant color MARV stretch goals, then move on to the first two add-on kits (Zombie and Apocalypse). All MARV vehicles would share the same load outs, paint highlights (dash and lights), assembly, and packaging style. If this project is successful, I will keep an eye on demand and potentially explore alternate ways to offer the base MARV and/or individual parts.
