Just finished installing most of upgrades available for w213 on the market.
still have to install the GT 4 door style LED AC vents for front and rear, and headliner LED speaker.
im sure its not everyone's cup of tea, but I think it freshens up the interior of the e class. It definitely brightens up the interior quite a bit, as I had to turn down the brightness to around 60% or so.

 

Not sure what I'm looking at, upgrade-wise.. Is it the addition of LED bulbs or the upgrade thereof? .. I'm in the dark as I'm about 3-4 weeks out of taking a '23 All-Terrain delivery. .. Your upgrade looks great!

 

Installed the sunglass holder overhead console speaker, mod range speaker covers on the doors.
also strips on the back of seats and tweeters.
I will post updated picture, once I install the vents this weekend.

 

Any links to the products used? Interested in the seat back strips.

 

This Ebay seller in US. Highly recommended. He also sells coding stuff to activate hidden menus, like fragrance.

I just did the air vents. The driver and passenger side reflect a lot at night on the windows. Beware if you do, but they do look nice!

 

yep. I had to lower the brightness.
