So Tesla is currently offering 1.99% APR financing on new standard range and long range Model 3’s that are not eligible for the federal EV tax credit at this time:

That’s almost free money.

You can also extend the loan term to 3 years:

I was curious to see how the numbers might play out realistically.

Using round numbers, 

• The base model standard range rear wheel drive Model 3 can be had for $39,000. 
• Let’s assume zero money down for a full loan amount of $39,000.
• The loan would end up costing about $1,000 in interest over 3 years for a total loan cost of $40,000.
• Suppose I took the $39,000 I would have paid cash for the car and put it in a high-yield savings account currently paying 5% APY. (See disclosure below following post.)
• Let’s also assume you’re making the monthly car payment (about $1,100) from your earned income so you don’t have to dip into the savings at all. 
• 5% is pretty juicy right now in 2024 but it may not stay that high. Let’s be pessimistic and say rates might drop 0.5% each year over the next 3 years, i.e. 5% > 4.5% > 4%.
• The $39,000 in the savings account earns me about $5,500 in interest over 5 years, growing to about $44,500, disregarding taxes.

The salient takeaway here is not that it’s then suddenly a cheap car (it’s not) or even that you should buy one, but rather that, via some simple, virtually riskless interest rate arbitrage, you’ve effectively reduced the initial price by about 14%.

In the interest of full disclosure, this does again ignore taxes on earned interest, which is going to be highly personal, but it also ignores gas savings, so those probably easily cancel out. 

At 10,000 miles a year, $4/gallon, and 25 mpg, that’s a gas savings of $1,600 per year for a total of $4,800 over 3 years. Electricity costs for charging should be about 1/4 of that, so if we really want to be comprehensive, that’s about an extra $1,200/year in gas savings, boosting our initial price reduction calculation from 14% to 23%.

Note that the advantage of utilizing this financing offer does NOT require having $39,000 cash on hand, which admittedly may be unrealistic; that was just my hyperbolic example to illustrate the opportunity cost.

It works the same on the other extreme. As long as you have $1 more than the minimum monthly payment, it's advantageous to put that $1 in a high-yield savings account as described for the interest rate arbitrage. That's sort of the whole point – here it makes objective sense to utilize the low-interest debt and pay the minimum monthly on the loan. Obviously if you can't afford the minimum monthly payment, you shouldn't be looking at this car in the first place.
