5/31/2018 Update:
On day one, I emailed pictures of the body scratches and other faults to Cheri. I emailed some additional ones since then as well. There are a lot of scratches. She doesn't generally respond, but I assume they are reviewing the pictures.
Chris, a "Customer Care Advocate," called me fairly quickly after my e-mail to Cheri, and I've talked to him on the phone twice, and also briefly in email. I informed him the 75th Anniversary package is a nearly $5,000 package that includes a steel bumper, a 6.5" touchscreen with UConnect, and leather-trimmed, heated seats (and several other options). The Jeep they brought me has none of those. I spoke to another gentleman as well, but he was talking in circles, and I did not receive any useful information, other than "the price is correct." Chris did admit the text description was changed after I bought the vehicle, but cannot explain why. It was something close to, "We get information from the VIN and other sources."
What I'm hearing so far is not encouraging. They are supposed to have complete information for me tomorrow about how to settle this. They extended my 7-day review period until 5:00 PM tomorrow (Friday 6/1), so they have time to try to address these issues.
6/9/2018 Update:
So Carvana offered me $600 back total to buff the scratches out of the vehicle (some are buffable, some are not) and also for the cleaning. They offered to order floormats but only after my 7-day "trial" period, which I did. They haven't arrived yet, and my carpet is getting very dirty. I also ran into a new wrinkle. Carvana keeps the vehicle registered under THEIR name the entire time you are making payments. This complicates vehicle registration if you have a personalized plate, like I do. It's possible to keep your personalized plate by sending them some information, but it does make the entire process more complicated than simply going down to your county clerk and transferring tags.
Would I do it again? Under most circumstances, I would say no. However, the vehicle I bought is a Jeep Wrangler, and getting a good deal on these is very difficult. They are wildly popular and hold their value so much that late models go for nearly new price. This gives Carvana an advantage over most dealers and individuals selling these, which is why I kept the Jeep I bought. In my particular case, because it was a Wrangler, I simply couldn't find a significantly better deal. I did find a much better deal on eBay, but it was in New York. I'd be buying long distance. I'm not a fan of that.
So bottom line, don't think Carvana is "no hassle," because it can be a great hassle. Also don't expect a vehicle that has only the scratches/damage that they identify on the web site. There will almost certainly be more, based on my experience. I've rated them up to 2-stars, due to the fact that the price was unintentionally more competitive and I have to acknowledge it wasn't a bad deal (or I wouldn't have kept it obviously).
Overall, though, the process was and still is a hassle, and I was slammed with disappointment when I first got the vehicle, due to the listing "error" and the additional scratches and dirty interior/exterior. I also really dislike that I don't receive a title and they keep it in their name. Why is that? Is it because it's easier to repo a car if it's in their name? Who knows. They didn't explain it, and I didn't see it in their FAQ, but I don't like it.
Bottom Line: No, I would not recommend this to a friend
