suggested price from a few car sites are 10-12% off MSRP new, and given it being a loaner - many having closer to 10k miles due to short supply from the pandemic - i dont see why 20% isn’t attainable.
production is getting better for all car makes so they should be very willing to move them with replacements on order/delivery
Not stackable:(
Fleet incentive has never stopped.
20% off a loaner is not as easy as it used to be. I spent many hours and emailed many dealers to get past 20% on a loaner 5 series. I think the E class even tougher
I thought the fleet discount didn’t apply to loaners.
I was guessing that the dealer either applied fleet when they shouldn’t have or they just wanted to get rid of the car and just took another 3k off themselves.
I think @Calvin.MB is confirming fleet doesn’t apply to loaners?
I think the 2k lease cash cannot be combined with the 3k fleet is what he’s saying.
MB does allow fleet on loaners, I believe it was that the dealer would chop up the incentive where portion was already applied to the vehicles discount or something along those lines - and when submitting paperwork thru finance, they still applied full incentive causing the dealer dilemma (internally)
If he can set it straight - please do.
In the end I think the fleet plus ~15% off isn’t bad at all, and if you can pull the 20% as many are hoping 
They do allow fleet on loaners.
Regular incentives do not stack with fleet incentive
Let me share some useful information which can help others to find a good deal:
my car was found on sonicvipservices.com website. Before contacting the dealership it was listed in the website already with %20 discount. Plus minimum money factor, fleet rebate & MSD made this deal unbeatable. It’s hard to find a good car / spec-ed loaner with good MSRP discount and good fleet rebate. Money factor is negotiable with dealership if it’s too high.
Good luck to everyone!
That’s right, it’s not stackable. I checked in edmunds website, incentive was 2k for that car, but fleet was 3k. Used fleet with more rebate.
I believe fleet incentive it’s not something you can negotiate. It depends on the company you’re working for and the fleet Mercedes has for your company for that particular model/year, it goes per model per year. Yes, I guess if MB wants to get rid of the car they will give higher fleet rebate on that car.
When was it ever easy to get 20% off pre-incentive on any car?
I looked at the sonic site and where can you tell which one is loaner? Also was it Walnut Creek you got your car from?
Never easy, but if I remember correctly, I’ve seen a few broker ads where mid level luxury sedans were over 20% off. Think during the last month of lease support? Don’t think I saw any this year though
Only said it because you said: 
Awesome Deal!
This is a strange site. Some of them don’t have MSRP and some don’t have sales price. None have both lol
How were you able to calculate what had 20% off MSRP? Also I assume the loaners are listed as used on there right?
My sale agent found this car on this website. He sent me the car spec with MSRP price then I was able to calculate the discount. My agent is based in LA, but was able to deliver the car from NoCal to LA with no cost for me.
I think they marked as used/certified with about ~2-5K miles. I’m not sure what is maximum mileage MB allowed to lease the cars, I guess it’s around 5-7K.
It’s 10k miles. Or maybe even more, but mileage penalty will kill these deals.
Interesting Spec, no pano roof or 19’ wheels but adaptive cruise and air suspension? Probably the best spec for comfort driving! Great deal, a couple months ago I looked at a very similar MSRP '20 Loaner E350 and they were at $700/mth. Good to see some dealers are more realistic!
