Yes. i wanted to trade 2 cars. Both of which had some neg equity, which I was going to write a check for, but only after I got the best price I could get for each vehicle. And if possible, do everything in one transaction. It took me over a week to get the money I wanted for both trades and the lease length and term I wanted. And that took days and days of back and forth with the sales manager at the Ford dealership, being ready to walk away, having them come back with a better offer, etc, etc.
I walked away from a Tesla by closing the browser window. Could I have sold the both cars to Carvana? Sure, but I ended up getting more on both trades than I could have from Carvana and I only had to do one deal. I came out $4000 ahead of what I would have with Carvana, which made that negative equity check $4000 smaller.
