My MB c300 lease is up in 2 month, looking for tips in order to get a good deal (Florida)

Hey, my lease will be up in the end of October and I would like to upgrade to an E class, I don’t have a problem with getting a loaner in order to get lower monthly payment.
What incentives should I ask for? what discount off MSRP should I target? any other tips that will help?
Thanks in advance

Search for similar E class deals in the forum for discount achieved. Incentives and MF will vary by month.
