Recently I purchased a 60kwh model S through my clients who own a car dealership. They purchased it via OVE. When we received the vehicle it was actually a 40kwh model S instead of the advertised 60kwh. Through a number of circumstances we're stuck with the vehicle. I love everything about the vehicle except for the mileage. Does anyone know of a more reasonable way of getting the full 60kwh capabilities? I called Tesla and they told me the upgrade would be $11k regardless of my unfortunate situation. Please help with recommendations if possible. I'm in the Dallas, Tx area
