Hello. I'm on the fence for my Model X to buy vs. lease. The geek in me says to lease since I'll probably want a new car in 3 years. But the finance part of me wants the full value of the tax credit. There are a lot of calculators out there but few have a place to input the value of the tax credit. If you know a great site or place to download an Excel calculator to run the benefits of one over the other, it'd be so appreciated!
