Carvana complaint: bait and switch

My complaint is about the absolutely disgusting and borderline predatory business practices of Carvana. I am disabled, which means I don’t have good credit or high income, and dealership shopping isn’t easy. I did, however, work long and hard, even borrowing an amount to put a large down payment for my dream car. Carvana DOES make it easy to purchase a car… but everything that follows will be an absolute nightmare. First, I was given a timeframe for submitting my insurance documents and took the opportunity to shop around. I was told I had until the X date, but on Y date about 4 days sooner, I was contacted to say I only had 24 hours to submit the necessary documents. After doing so, I was contacted by the registration department, who informed me the start date on the insurance binder was incorrect. I had to have my insurance agent again rewrite the entire binder with just a few hours notice. The communication is abhorrent and essentially non-existent. Fast forward to the date of my vehicle delivery, it arrives in filthy condition both inside and out with a sickening odor inside, undisclosed body damage, as well as completely missing key features that are advertised via the window sticker and VIN. As I said, being disabled, I sought out very specific features that are necessary for me, and these smart features were the main selling point of this vehicle for me. I would have otherwise never bought this vehicle, and I even went out of my way to the features with the sales department before purchasing. Carvana has attempted to write this off as a misannotation when that is impossible, if the vehicle was actually properly inspected at any point. The resolution offered was a swap for a higher priced vehicle that has the same features, aka bait and switch. I had to fight for 4 days to have my case escalated to a supervisor who finally, insultingly, offered me a mere $500 compensation which is not even half of what it will cost to replace the navigation remote start, and will still leave me lacking many of the vital Smart features advertised. This will of course not cover installation fees or travel to these auto specialists, only the necessary parts. I am currently working with the warranty company to address the body damage, Carvana has offered partial compensation for pride detailing as well, but if I am not compensated in the minimum amount of $1,000 for the parts needed to make this vehicle accurate to the Carvana promised standards, I will persue further legal action after returning the vehicle. Carvana should be begging me to keep this vehicle and thanking me for even being willing to have all this work done, costing me additional time and efforts, not to mention the days long severe mental anguish I’ve experienced having what was supposed to be one of the happiest days of my life completely destroyed.
