No, no, no! This is very bad advice.
Stop listening to Dave "Formerly Bankrupt" Ramsey; he's for ENTERTAINMENT VALUE ONLY.
When money is on "Sale!" one should BORROW the money to buy the car, and leave the rest going into TSLA shares. Doing this has made all nine (so far) of the Model S's we've owned effectively free, many times over, but then we've been buying both TSLA and the cars since 2013 so you'll have to wait a while to see similar returns, but they're coming . . . . TSLA is at about a 33% discount from all time high.
Think about these choices people, THINK!
