Shoot for 15%, which seems to be the limit of what’s possible with Mercedes. Then seek any incentives. Fleet is $1,000 on E Class I believe. Look at the deal that was just posted on a P1. He was able to obtain a payment of around $430 with just fees due at signing. That should probably be your target, but may be a challenge to replicate.
Nil,
I am the person that got an E300 4Matic with an MSRP of 59,775 down to $429 with 1946 out of pocket (in addition to the 4500 in security deposits). Since your car is spec’ed out almost $3,000 cheaper, I would think that you should be able to get the car for about $400 a month. As for MF, after paying the 10 security deposits, mine was 0.00036. I do not know if the deals on E300 will change in April or not.
