It's already in the market. It's not a case of 'putting' money anywhere, it's a case of pulling it out to avoid 2% interest. That makes no sense to me. I'd rather get a 2% car loan and leave $60K in the market earning 8% - 10% or whatever it will be.I'm not sure I'd call it "stupid" really.
If there was somewhere where you could get %5 or 10% for your money then maybe, but then again, the car loan would be equally high. TBH I think paying cash and getting a tangible asset (which appears to not decline too aggressively) is a good hedge against a possible inflationary spike. Also if you had the cash available, where would you park it wile you serviced the car loan? put it in the market and you risk losing a significant portion of it
Just my opinion of course
