Your credit picture, rate sources, and one flag before you sign
Advertised rates assume strong credit, roughly 750 and up. If your score sits below that, or you just paid down balances that have not reported yet, your first quotes may run higher until your credit updates. The primary borrower's score sets the rate, so apply under whoever's is higher. Use the "credit-tier rate bump" above to model a higher tier, or drop your real pre-approval APR in once you have it.
Heavy-SUV tax note: if the vehicle clears 6,000 lbs GVWR (the Model X does) and you use it for business, ownership matters. Whether you buy it personally or through a business changes what you can depreciate, and it is hard to unwind after purchase. Worth a word with your tax advisor before you sign.

Rates as of July 8, 2026. Navy Federal used-car APR by term: 4.79% (12–36 mo), 5.29% (37–60), 5.39% (61–72). USAA used figure is its published 60-month rate (5.99%, or 5.74% with autopay), held across terms here; your pre-approval prices each term exactly. Tesla 7.19% is the listing quote. Sales tax is estimated on the full price at your set rate; California gives no trade-in credit. DMV and doc fees are extra. This estimates financing cost and is not a quote.
