Just want to give a little shoutout to Carvana. I know others have had pretty good experiences with Carvana, and mine went extremely well, too. Almost too well, really. I know y'all are likely working with some timing challenges, having very little information as to when you'll finally get your new Y, which makes doing something with a vehicle you're looking to replace a lot more difficult. We were of course in the same boat. That said, we worked with the Tesla EDD windows we received and once it started stabilizing (yeah, we got the occasional nondescript months and week ranges from time to time as well), we started shopping around our previous car. Our 2013 Pathfinder had served her time admirably, but it was time for her to add fulfillment to a new owner. Our valuations from Tesla and Carmax were right around $12K, but Carvana came through with about $15.4K...which is meaningfully higher. We got our quote in July (when the delivery was hovering around the 8th of August), and the quote expired on the 13th. Well, of course our EDD kept pushing back...but fortunately, Carvana honored the offer for a future delivery. So we were ultimately able to schedule pickup of our Pathfinder on the 10th (prior to the quote expiring) for the 27th, which we felt would be close enough to taking delivery to our Y. As it worked out, we picked up our Y the evening of the 25th, so it all worked out.
On the 27th, we had someone from Carvana come out, take a quick look at the car, take it for a test drive around the neighborhood, and then we signed a MVPA, she put a lock box on the car, and said a tow truck would arrive a little later to pick it up. But when she left, the car was theirs and she had started the ACH transfer (there was an issue with the check printer she had with her). Of course, a tow truck came buy and picked up their car and there she went. Funds arrived in our account this morning and we're all done.
I know the whole balancing of your trade-in and taking delivery of your Y can be a stressful endeavor, but wanted to share with you our experience with Carvana. Like many of you, I hadn't had any experience with these online-only car sales companies, but our experience was fantastic--it definitely relieved at least some of the stress of the whole experience.
