Build Date
As E53DadWagon said, check around with other dealers...they may have earlier allocations that can still be changed to your spec's. Your dealer may have other customers that spec'd their earlier allocations, or they could have spec'd them for dealer stock.
All that said, we are in unprecedented times right now. MB may be prioritizing other countries and/or other models until they have solid answers regarding tariffs.

Many factors go into production, including parts availability, supplier shortages, etc. Builds are organized into monthly "decades" with 3 per month, and the decades can consist of one type of vehicle or varied production. The latter is most common. The factory planners know when they can build cars and schedule accordingly. The process is usually automated, but sometimes humans are involved. US production is also different, requiring different components, certification labels, etc., so many times production of US/Canada-bound vehicles is batched together, which can result in increased lead times.
Then there are also build issues. Sometimes, the factory will postpone builds in order to account for supplier issues. As an example, my same dealer just ordered an E 53 sedan for another client, and the production slot assigned to that car will not accommodate either 21" wheel option, owing to supply issues. The customer originally opted for the 20" wheels and a corresponding slot was assigned that could accomodate ALL options + 20" wheels. Their desire to change to 21" now means the dealer is requesting a revised date. (The process for ordering is a little different in Europe.)
Your E 450 build date is likely the earliest allocation the dealer has, along with the earliest date your options can be accomodated.
I know in the US allocations are based on a super secret, overly complicated formula that weighs dealer size, location, performance, history, blood type, etc. but it is super simple for a dealer to trade with another for an earlier slot. Ask your dealer to do that. Many order cars for inventory and don't care if it arrives later.

As opposed to say wanting a Panoramic roof, and getting a car without it, and then trying to retrofit it…..which is next to impossible, without drastic and unsafe vehicle surgery.
Maybe the above person should just order with the 20” wheels and just swap it to the 21”s, after getting the car ?

Very few dealers keep cars on the lots, so since you're custom ordering anyway, you add everything you want at the start.
EDIT: As an example, my Volvo wagons have spacers installed. The size of the spacers and the TUV certification number for them are listed on my registration. Additionally, my cars came with 2 sets of wheels - 1 winter, 1 summer - as part of the factory ordering process. The "remarks" section on my registrations also indicates this, showing the winter wheel sizes, tire sizes, and load/speed rating. The summers on the V60 are 20" while the winters are 19". The V90 has 21" summers and 20" winters. They mean business with this stuff.

The picture with the rooftop box has the OEM staggered 20” wheels (with Michelin Pilot Sport A/S4 XL-rated tires) while the bottom picture has the 19”s that came from the factory. Easy swap out, swap in.
Like with all roof-boxes, this will also exact a mileage penalty. The E450 All-Terrain typically gets around 32-34mpg, consistently, with a higher content of highway miles. But with the roof-box (and the car loaded to the gills with stuff), during a recent 1500 mile trip, the mileage dropped to slightly under 26mpg, which is par for the course, I guess.

The email goes on to say that they are awaiting an allocation from MB. I could have sworn they said they had one or could trade easily for one. Or does it mean that even though you have an allocation, you still have to wait for MB to give it to you?
Any help on the exact process for what is involved in each step of a custom order with MB/AMG is most appreciated...
I understand that I still have a little time to lock in my exact order even though it was "accepted". I am down to deciding between Alpine Grey (which is on my accepted build) or Sonoran Brown for the E53 wagon color. Any info/opinion on either of these colors is most welcomed. I liked the Alpine Grey from the start of my search because of the "future cars" video from MB for the E53 wagon. But now I see that they offer this "exclusive" alpine grey color to all kinds of the higher end vehicles (sedans, wagons, SUV's, coupes). The Sonoran Brown looks to me like a classic wagon color but I worry that it will make me look like an old person (I am 50 but don't look/feel it). And it appears the sonoran brown is just being offered to the E-class and S-class sedans/wagons. Maybe the sonoran brown doesn't look good on SUV's and that's why it is only on the sedans/wagons...dunno. But any help making this final decision before locked changes is greatly appreciated.
I am going with black nappa interior because I really don't personally like the two tone tonka brown / black seat look. If MB just did all tonka brown, I would probably get that interior on both the alpine grey and sonoran brown exteriors. And the neva grey interior worries me with blue jean stains, etc.
Oh...and some of you that are on this thread and also other E53 threads had previously questioned the $5000 down payment i was quoted to custom order. The dealer I was originally going with said the $5000 was standard. The dealership that found me the best deal on price only required a $1000 deposit like many of you had mentioned that you had. I feel wayyyyy more comfortable with a $1000 non-refundable down payment than a $5000 one. Thanks to all of those that mentioned that the $5000 was not the overall norm.
