Thank you! There are 2 stages of this project -1.stage- individual builds from drawings and already built prototype examples and parts. 2. stage - small batch production of all wooden components and pre-selected, manufactured components. We are now in stage 1, where all expenses are 50-70% higher then in stage 2. So, now costs of platform itself consist from frame materials and electronic components, motors, batteries, suspension etc. Frame itself is around $500 - 700, together with essential parts and entry level motors, batteries total price should start from $3-5k. Adding sensors, chargers and electronic components might go up to $7-8k. Body modules are separate costs - mostly material +work. The truck cabin and flatbed modules cost around $800 in materials + couple days of work, so total costs might be between $1-2k. More advanced cabin or cargo module, with windshield seat belts and accessories might go up $1-2k more. Custom module builds, like passenger capsule version will be more expensive because it should be designed first. Hope this helps!
