Ok, need to come up with a chunk of money. I have options, just wondering what others are doing. 1. Buy the car outright. I can come up with the cash, but interest rates are so low it seems silly to not take advantage of the time-value of money and keep more of my savings invested. This isn't really an investing strategy question, but it comes into play. 2. Finance some or all through a credit union for lowest rates (1.74% at PenFed, and I'm a member already). Make payments. Drive car. Use cash saved to buy TSLA. 3. Finance about half through Tesla or whoever they partner with. Sales rep told me rate is a bit over 2% right now and has the guaranteed residual value and all that. He said I only need to make payments for 6 months to qualify for the guaranteed residual value. Then I can either pay off the car or presumably refinance to my credit union. I suspect the rates will not be as good when that time comes. Any suggestions? Option 2 seems to make the most financial sense, but Option 3 has peace-of-mind. Is the guaranteed residual value worth the extra $ for option 3? I plan to keep the car a long time. On the other hand, this car is new technology from a new company, so it does offer quite a bit of peace-of-mind. I'm leaning towards option 3 and the higher rate could be mitigated somewhat by financing a smaller amount. Thanks, comments appreciated.
