I was in a similar situation. You could benefit from reading the replies from my thread. FWIW, I opted to sell back to the dealer to avoid sales tax, the price offer is a little lower than third-party but my net came a couple of dollars higher due to lower dealer buyout (no sales tax which is in my case was 8.375%).
Goodluck! There’s a lot of opportunities right now if you don’t need the car or have a secondary one. Sold my 6MT to buy a truck and thinking to sell the current SUV to upgrade as well. Do it!
