My 2020 GLE250 57K miles engine has seized. It needs a new engine. Some questions

1. Prior to the failure, it was worth ~33K. Dealer estimate is 28K. Is it worth repairing then?
2. If I had to sell it, how much would it go for and what are the places that buy this?
3. Dealer is quoting 28K. They said they could bring it down to 26K. Its still high, will be asking for a goodwill offer from MB to further reduce the cost. Will it work?
4. Dealer is using a long block engine (12.7K). It comes with 2y / unlimited warranty. How does that compare to a new and used engine? Which of the 3 option is better?
5. To replace the long block engine, labor cost is 11K. Its 33h labor. Does it take that much?

Thanks.
