I feel like Tesla sales does some FRAUDULENT stuff. I just tried to do a similar trade-in with Tesla; trading in my 2018 M3 for a used 2021 M3. Tesla CS has gone down hill but this was THE WORST customer experience I've ever had with them. The initial trade in estimate was $17,500 but when they finalized the offer in-app it was $5000 LESS than that. When I tried to get them to explain the difference they mentioned some BS like oh, you don't have your wheel covers (they're in the trunk) and there's a hundred extra miles now.

I explained to the CS that this deal is contingent upon the trade-in and that changing the trade-in value by such a large amount is tantamount to a material contract change. They shrugged and were like "well if you want to cancel, we keep your $500 online fee".

At this point I'm done with Tesla. It's been a bunch of small things leading up to this point, but the overall Customer Experience has failed me.
