I had a thought today about the secret weapon that'll spur demand. Why do we have car loans that are 3-5 years in length? That's a remnant from when cars just wore out after 5-8 years of use and make ownership of a vehicle like the Model S unattainable for millions of would be buyers. We don't have 3-5 year home mortgages but our homes do wear out right? We preserve our investment with new paint, new roof, carpet, appliances etc. So, why not offer a Model S with a 15 year payment plan and service, warranty, replacement battery could all be rolled into it. Purchase price $95k, $85k financed at 2% is $550/month. Free fuel means average driver would save $200/month. Effective cost would be $350/month for 15 years. I don't know of any other car company that could even propose something like this because most of the cars on the road are a wasting asset by design. If you had an opportunity to do this would you buy another Model S, X or the 3?
