So, I got all my questions answered although it took some back and forth between me, the buy back representative and my dealer. My dealer told me they had never heard of anyone receiving a buy back offer on a 2 year old vehicle, but I did. I had my dealer review the buy back offer to make certain I wasn't dreaming. He agreed it was very generous.
I decided to place an order for a 2024 Nautilus. Between my dealer and the buy back representative, my buy back has been placed on hold. It will be reviewed closer to the time my Nautilus being delivered. This will probably be around 6 months from now.
Hi RH. Just one recommendation: If you have not already done so, be sure to get everything in writing, including the fact that Lincoln/the Dealership have agreed to the fact that your "...buy back has been placed on hold." and "...will be reviewed closer to the time my Nautilus being delivered."
It would be very frustrating (to say the least) to suddenly have them say your car no longer qualifies for a buyback 6 months from now, due to various possible reasons. For example...what if the Lincoln reps you are working with are no longer with the company in 6+ months.
Or...someone at Lincoln "reviews" your case, and decides your 2+ year old vehicle should never have qualified for a buyback, or no longer qualifies due to it being 6 months older.
If everything is valid and all of the intentions are good, they should have no problem verifying it in writing for you now. It protects all parties.
Good luck with whatever you decide to do and keep us updated.
