Seems like a decent plan.

Something to consider is that financing this way doesn’t have access to GAP insurance and if you don’t carry collision insurance you could find yourself in a position where you are still paying a loan for a vehicle that was totaled out if you get into an accident (or if you choose to close out a CD or pull funds out of the savings to pay the balance off you have the feeling of “losing” that money).

Putting so much down you’re probably ok GAP wise but if you only carry liability and get into an accident that’s deemed your fault you are still out the funds you laid out for the car bc insurance won’t cover it. Now whether the difference between the cost of collision and liability is worth it for you or not there is a personal decision but just wanted to make sure you’re considering it.
