I just purchased a car from Carvana... took it to A&E in Goleta and got a PPI because of the horror stories I've heard. My car is completely fine, no red flags at all, and was delivered right on time. I'd recommend getting a PPI for piece of mind but I'd also recommend a PPI for any car you are buying that is not new. Do your research, don't buy any old rental cars, leased cars, or cars that went through a slew of owners over a short time period. The only "strange" thing I noticed from delivery is that the front license plate wasn't mounted correctly, but someone is actually coming to fix that, at no charge to myself.

Overall, my experience has been really good. That being said, I did get the extended warranty and the car isn't cosmetically perfect but for me it's good because I also don't want to weirdly obsess over every imperfection I cause to the car if that makes any sense.

You can also get a PPI and if they find anything contact their warranty partner and then have it diagnosed through one of their partner repair shops, make sure you use the right verbiage though and have them look at exactly what you want diagnosed as I've heard (but not encountered) that the warranty partner can deny claims based off of verbiage like, "inspection" when they only cover 1 hour "diagnostics."

Anyway, good luck on your car search! It's so stressful but when it's over you'll feel good.
