I am thinking about a few upgrades for the C300 Wagon, including carplay and front camera. Do they have a good reputation, easy to work with?

I've used Andrei at MB House to upgrade my E-class, as I'm very picky about things. He also diagnosed and fixed issues with my father's S-class on an emergency basis
I can totally recommend him. He's an enthusiast, and works hard - I dropped off my car at midnight once and he worked throughout the night on it!
He has even lent me his own Mercedes to drive while he worked on my car - I don't think he does this as a rule, but it goes to show the lengths he would go to making his customers happy
I'm glad for his success. Give him a call

(No affiliation by the way, just a regular customer)

Dont know about them, called them up, their rates seem to be the same as the dealer rate, $160 per hour, whats the point, might aswell get the free carwash.

The benefit of MB House over the dealer is that they'll do programming and retrofits that the dealer won't do (I got my eco start-stop deactivated there) they'll also do the retrofits and cosmetic upgrades
