Now Vroom and Carvana won't buy your car in the last 60 days of lease not matter what leasing company you leased the car from. I have a lease with Chrysler Capital and they won't provide a formal dealer buyout letter in the last 60 days of the lease even though the difference (as what they told me over the phone) between the buyout that they sent me is that the dealer doesn't pay the taxes. After waiting on hold for over 8 hours, Carvana confirmed that even though I have a personal payoff letter from Chrysler Capital they wont buy my car - even if I told them to pay Chrysler the full price including taxes (ie just give me the net difference assuming they had the pay the taxes). Carvana's suggestion was to extend the lease for two months (I am in my last month) and then they will buy the car on the spot. Chrysler said no extensions being granted unless I have a new Chrysler vehicle on order. If your lease expires in the next 90 days - go to Vroom/Carvana, etc. now and see what the price is to take advantage. In my case - excluding taxes, Carvana and Vroom offered $4500 above my lease buyout price.
Obviously captive leasing companies want to take advantage of the current white hot used car market and not let the consumers take advantage.
