2018 Polar White E400 Wagon

Figured I'd start one of these (it's been a long time since I've done any build/mod thread on forums), but I do love this car alot, even though it has its nuances.
For Starters, I bought earlier this year a 2018 E400 Estate (Wagon) after about 4 months of searching. Had a few Criteria's, including PP1 and AMG Line Exterior and mileage under 60k. Was looking for a Blue on Brown for quite some time, and had given up that they even existed. Most of the Blue's had the light macchiato interior, which having 3 kids, didn't quite suit me. Surprisingly, when I was looking for this car, the process reminded me of how LAZY dealerships are, especially when you are from out of town. I was looking nationwide to find something and the amount of people that had given up or not even responded to me after a phone call and email looking for some specifics was staggering.
Right before my family went on a long vacation, I was casually looking again (as one does when they are on the hunt) and one popped up locally in the Houston Area, at one of the big Mercedes dealers. No picture, only description that it was a White Wagon with nut brown interior. I frantically called and got an appointment set up to go see it. My sales associate, who couldn't for the life of her understand why I was so excited to come see a wagon 1 hour before they closed, understood after I and a few of the employees told her about the "cult" status. It had just come in for a trade, and apparently the owners got a new s214 wagon for trade.
Even though it was Polar White, it looked great, considering it had the AMG Line AND Night package. After driving and taking a bunch of pictures and assessing all of the damage (keep in mind it had some dings and some light curbage and old decals from the previous owner), I was assured it would all be taken care, and it was. It took them about 2 weeks (so it was good that we had go on a long vacation), and they fixed up what was required and what I mentioned (including new tailight, headlight, refinished wheels, interior panel replacement, gas cap and purge valve). I was called to come pick it up and it was a beauty!
The car drove great and I was quite happy with how it drove on my way home, although I was very careful. Houston Roads have the tendency to potentially have an entire furniture set laying on the side of the road so I was even more careful then usual. (side note, when I was driving my wifes car home from the dealer there was a dump truck in front of me and I couldn't get away from behind it and cracked her windshield 20 minutes into ownership).
Once I brought it home, it was time to sell what was my daily at the time, a 2011 Jetta Sportwagen TDI. It was a great commuter car with almost 100k of worry free miles under my ownership (and looked great).
I have an itch for modifying the cars, so I started doing research (or well the limited research available on this chassis). Had a vision of what I wanted it to look like, but again, not much information for stateside, more-so for European models.
One of my favorite features, and really the entire reason that I went for this wagon was for the rear facing 3rd row. Like mentioned above, having 3 kids, it is impossible to fit 3 across any non giant SUV, and I do not care so much for SUV's as my primary modes of transport. My RS4 barely doesn't fit anyone in the rear seats (let alone a Doona Baby Stroller/Car Seat and normal car seat or Booster). I would have considered the E63S, but unfortunately no 3rd row, and retrofitting by cutting out the support beam was not in the cards from a safety perspective.
Quick Run Down on the Factory Options:
149: Polar White
124: Nut Brown/Black MB-Tex (for 3rd row)
736: Natural Grain Black Ash Wood
737: Center Console in Natural Grain Black Ash Wood
P01: Premium 1
322: AMG Line
521: Night Package
591 3-Zone CC
Thanks for reading and hope you stick around for the journey!
Here is how it looks like now!

1) Suspension
The big complaint that I kept reading was the car didn't feel sporty, and almost land yachty. It had some body roll when taking tight turns, but I didn't quite see that it was that bad. If anything the Pirelli Run Flats were really the weak link.
2) Wheels
I was never a fan of any black and silver anodized style wheels, ever. I always thought they and are gaudy, and my initial thought process was to HyperDip them gloss black. Additionally, these being 18's made them look undersized, considering the length of the wagon. I had BBS on all of my previous cars, and was looking to do the same (CH-R's to be precise for this model).
3) "E43" Inspired
It is very annoying that the E43 wagon was not sold here, yet remains virtually similar to the E400, minus what I surmise is a more aggressive tune. Therefore I wanted to take inspiration from the overseas model (without upbadging) and perhaps a mild Tune and TCU programming for an extra 50-70hp. This includes minor trim pieces, OEM + style. New Grilles, diffuser, exhaust,etc.
4) Long Ownership
Trying to keep this car for a long time, therefore I will also be documenting little problems I or the MB dealer/Indy shop find.

Regarding the black trim, I think if the badges were black it'd be a necessity. I am probably going to keep the factory mercedes emblem, in which case the chrome above the rear taillights, the door handles and the chrome ring I left around the grille will be enough of a touch to bring it all together.
I will make a post later on with the before and afters for all of the things I have done to the car. Waiting to see when the spam filter stops blocking my posts.

Car fully loaded up, 2 girls in the rear seats, and my older son in the bench seat, we got side swiped by a young distracted driver who tried to avoid the car in front of me stopping short and swerved into me and i swerved to avoid him and got pushed into the guardrail. (He ended up hitting the car he was trying to avoid after bouncing off of my car).
Hope to get some news back from insurance soon. I am going through my own insurance as the insurance company of the at fault driver, is nothing less than absolutely awful when it comes to claims.
Heres some pics, any insight would be nice. I am quite concerned about the right rear quarter being the most damaged, hoowever the car drives straight and apart from some scraping of the front bumpers, it doesnt look too bad.
From my knowledge, this is waht is damaged:
- Scuffed rear bumper
- Scuffed front passenger door
- both headlights broken
- both fenders are busted
- hood is dented on both sides
- front bumper is broken
- both rear quarters have obvious damage
- driver side mirror is clean broken (hanging on by wires).
- all 4 BBS CI-R's are scuffed. Driver front has the worst of it.
At the end of the day, I am of course happy that we are all safe, even though it scared the crap out of us because we were literally just minding our own business and then BOOM, but the car did its job.
I have already arranged that the body shop of choice I will be taking it to is the Collision/Body shop with the Mercedes Benz dealer I bought it from, so if they decide to fix it, it will be done correctly.

in my experience, polar white is so much better than diamond white metallic designio to blend and to match

No matter how "perfect" the repair will be, in all future Carfax reports, your car will show extensive body damage, which will dramatically affect in a very bad way the resale and/or trade in value of your car.

Tomorrow it is being towed to my Mercedes Benz Dealers Collision center. Should be interesting as they are very thorough.
I do love the e400/e450, but part of me now is exploring the E63S if/when this one gets totalled out. Of course the RS4 would go if I bought it, but it would be something to entertain.
I do like the 3rd row seat, which the E63 doesnt offer, but my middle child is growing out of her car seat and will be in a booster soon, so I think it is manageable (at least I keep telling myself that).

consider this sticky if you decide to go to the E 63 route

My representative also was of the opinion after they do the tear down, it will most probably be totaled.
Such a shame. The Polar White on Nut Brown was really tough to find with everything else aesthetically and mechanically in shape.
I expect to hear the final verdict by early next week from Insurance.

Insurance has declared the car a total loss, with approx. 27k worth of damage.
Unfortunately if not for the cosmetics alone, the driver side suspension was damaged and the steering box (5k by itself) needs replacement. Really truly a shame that such a well optioned S213 is now off the road for good.
As of now I'm just waiting for the payout amount. Unfortunately my plans for buying a new car have been put on hold as my wife's ageing Q7 has now started suffering from Audi-itis and everything is breaking left and right, so her car is first up to get replaced. I will have some more fun driving the RS 4 around for now until things settle down.
@belugawagon sorry for your loss. I've never been emotionally attached to cars, houses or any other inanimate object but I would be truly sad if this happened to my car. I'll never find a deal like I got when I bought it.
On the Audi Q7...my independent mechanic only works on German cars and he tells me that Audi and BMW keep him in business. His wife drives a Mercedes.
