I used to be a maintenance technician at a third party automotive manufacturing facility. We sold fuel pump assemblies to Chrysler for new Dodge Durangos, Neons, etc. our contract with them stated that for every vehicle that came off the line and did not start because of our fuel pump assemblies, we would be fined the price of the vehicle to make. Durango was 8000.00 at the time. I believe they were selling for between 30,000 and 40,000 depending on options etc. The Neon was about 2000 or 3000 and were selling for 13000. This was about 15 years ago but the model is probably the same.

The answer seems simple then. Just become a distributor and then share with everyone how much you get the machines for.
