If you want to sell kits, first buy a kit. Build it. Ride it. Fix all the little problems that they all have. Then when someone asks you "How much and where?" tell them this much and me. If you know nothing about MB's you really dont want to sell them untill you learn. You will have an angry mob of people hounding you all day saying this broke and why wont you fix it for free, probably losing money, and/or respect.
