1. I would not keep the loan for 84 months. As I said in the OP, I am presuming the rates will go down. Yes, this is a PRESUMPTION for purposes of the exercise.
2. I'd rather pay the least cash for a depreciating asset. Someone mentioned a 3-year loan. Why? Wouldn't I be net positive leaving most of the money in the market over the same period? 6% loss on a loan versus 12% gain is a net gain. But this is where I get lost in depreciation/interest. I am missing something here and this is what I am asking about. Maybe 3 years is the sweet spot. Honestly, I am not even sure what I'm trying to accomplish here.
3. I am going to get an electric vehicle. On balance, right now seems to be the best time in history to do that for this or any other EV as far as pricing goes.
4. I know it would be smarter to buy a 12 year old beater with 150k miles and drive it as long as possible. We all know cars are a waste of money, etc. No one ever needs a new car. This is not what I am asking about.
We probably won’t see zero percent fed funds targets for a while. Don’t factor that into your math.
You’re drawing some relationships between the value of the asset and the amount of your obligation that are illogical and twisting you into a pretzel.
1. You’re buying a utility + enjoyment for a period of time that is uncertain, but will probably be at least 4 years.
2. Doing so ties up your cash flow in different ways depending on how you choose to make payments and this cash flow could have been used for other things.
3. You will have a depreciating asset that you can sell at any point. Your optionality might be precluded by your cash position, though, since you’ll need to free up a sum of cash equal to your current obligation to do so.
These three things are not the same things, and any one of them can function independently of the other two without the constraint of liquidity. You also have the same three things with your current vehicle. Also independent of the above three things and each other in the same way.
It all comes down to cash flow over time. You could wait 4-5 years and put those payments into an interest bearing account that earns over 5% and buy the current model of that car with cash, assuming prices don’t go up. You’d save yourself a couple years of payments.
The four years you go without utility+enjoyment are worth something, though. Figure that out and you’ll figure out whether you should do it or not. That’s the only rationalization that actually makes sense.

I found this calculator to be interesting and I played with it some, so check it out here:

Basically, I ran a 40K at 72 months at 6% w/ zero down vs making the equivalent of that car payment (~$663/month if that's right) right into investments at 12%. Long and the short of it is that during that same span, you can either SPEND over $17K in freaking interest alone (is that right, guys?) over that term, versus making ~$13K in interest at 12%. So even with your scenario of a 6% loss versus a 12% gain, you still end up with a 4K deficit.
Correct me if I'm wrong folks since I'm a total finance jong, and like I said, really don't understand this stuff fully. I just know I like to make interest instead of paying interest if I can help it.
Yeah, that math isn’t working. You’d be net positive over $20k in that scenario, mostly because all payments to investment are 100% principal and your payments to a lender are inclusive of principal and interest.
Not a lot of easy, risk free, 12% investments laying around though.
