So when negotiating for the $61k E class. Do I negotiate down to $52,000 and then ask for the FEP deal and THEN stack the $3000 bonus cash? (This would be amazing! Bringing the $61k down to $45,000) 
Hi Alex,
I checked with a source, and it turns out the FEP incentive cannot be combined with the Winter Event certificate. Also, dealers are likely to have already included the $3,000 Winter Event certificate in any quote they provide.
My apologies for the confusion; I’ll update the article to reflect that. I suggested in this thread, however, that one could try using FEP as a negotiation tool.
