The ONLY reason, IMHO to go with leather seats on a MB is to be able to get ventilated seats. I have standard leather and ventilated seats in my 2016 C300. The Cranberry Red leather is wearing really well. The leather smell isn't important to me, to be honest. MB Tex is actually comfortable and much more durable. But I live in Florida, where it's hot and muggy most of the year, so Ventilated seats are a godsend. As to the wood and leather steering wheel, it's nice looking, but if you wear rings, like a wedding band, I found it annoying in the 2012 E350 Coupe I had it on. That's an option I can and have passed on in my current car and the E450 build I have put in.

I'm glad you're enjoying both options in your car.

Ps: your seat bottoms look like they are in need of a good cleaning. I'm too OCD to have light colored leather as I'd be cleaning mine every day........LOL

We have the $1600 leather seats in macchiato beige in our wagon (they should have called this ivory). The carpeting is black and it shows a lot of dirt. The dash, steering wheel and upper/lower door panels are also black. The black on the lower doors dosn't show scuff marks the way it would if it were all macchiato beige all the way down.

I had MBTex on one car - never again. It is terrible stuff in a hot climate because it smells like plastic and does not breathe. Even solid leather breathes a bit to reduce the moisture between a body and the seating surface. Ventilated leather is the best. My Machiatto Beige seats look new as does the black carpets after almost a year of daily driving. They get vacuumed once a month along with the rest of the interior. The exterior gets a coat of Meguiar's Ultimate Quik Wax once a month as well.

It's all personal preference. I want leather and ventilated seats for the obvious reasons like you as it's a hot environment here in Florida. My partner on the other hand prefers MB Tex, which is a bonus for me as it saves money!

Wood/Leather steering wheel is great, I will make sure my next car has it.
I have the MBTEX in mine and I had a loaner with the ventilated napa, the MBTEX is very good and comparable to the cheaper leather in other German sedans. That being said, the smell and feel of the real leather combined with the ventilated seats really takes the car up to the next level. I will try and get this on my next car.
