Hi All
Newbie here.. so please be gentle :)
I am in the boat of deciding whether to buy a new Model S or Used (either CPO or private party. I have been struggling with the economics of used car purchase especially with the federal and state credits at play. It seemed like there is a big disconnect between seller and buyer expectations for used cars.
So as an analytical mind, I decided to create a quick worksheet for some quick comparison.
Question at a highest level I am trying to answer is 'Should I buy a used or new Tesla Model S?.
Please see this Google Sheet I have created Tesal Model S new or Used Calculations
Some things to consider
1. Please avoid editing this online version. Just download the Sheet if you find useful and edit there.
2. If you HAVE to change values, change the cells in green. But please undo the changes so that others can comment
3. I am sure I have made mistakes and left out some costs. So please let me know
4. I am assuming 3 years of ownership as a rough point of reference for comparison
5. Extended warranty purchase would really depend on age of the used car. A 2016 an older may not need it for example
6. Not sure of the Resale value after 3 yrs.
7. This calculation doesnt take into account the fact that newer cars have better hardware and more standard features.
8. This doesnt take into account the smell of new car as well as the excitement of new vs old :)

So looks like buying a new car is actually the way to go especially till the Federal and State credits are around.

I am really looking forward to your thoughts. Like I said, I am sure I have made mistakes. So please be gentle :)
