Well… On-forum, it falls somewhere in between run-of-the-mill and bad. We’ve certainly seen worse. Off forum, it’s not that bad. Context is key. If you do a quick forum search on the E300, you’ll see why. Audience is also important – forum members don’t create accounts to hack ordinary deals. So expectations are certainly higher here.
I really can’t support the idea of throwing money around and betting on lease assumptions. But yes, I agree that this could be the right car for someone. Time will tell. If not, you’ll want to consider adding an incentive and seeing how it plays out. Just be mindful that the longer it sits, the further you fall in the hole. We’ve seen a few marketplace deals where the OP didn’t budge, this one comes to mind: Audi A6 2017 for $516 per month
Food for thought, in any case.
