New Guy Intro
While the E39 felt like the fastest car I ever owned, the 550 is the fastest car I’ve ever owned. No drama, just goes scary fast … faster than my ’69 Dodge Charger 440 (no longer own it, it fell apart one day on a trip to Yosemite) , and it just feels extremely competent . I can’t imagine what an E63 must feel like, but I will find out.
I do like to mod my cars and have made several cosmetic changes already. Question for the board, is there an aftermarket tuning company (ideally US based) that has a relationship with Mercedes similar to the Dinan/BMW relationship? Most of my Dinan mods were put on at the BMW dealer and covered by a joint Dinan/BMW warrantee. I’d like to upgrade the exhaust system as a start, but don’t want to mess up the CPO warrantee. Any thoughts/suggestions?
Thanks, Mike

Thanks for the welcome. Sounds like your experience has been pretty positive. I hope mine goes as well. So far so good.
(Based on your screen name, I'm guessing you're in Texas. Lets hope Bernie takes his $25M + and signs off on the F1 race.)
I have heard elsewhere that Brabus is the way to go. Anyone have experience with Brabus and a CPO warrantee?
Thanks,
Mike
As far as tuning, there are tuning companies like brabus, or rentech, carlsonn ect. But I personally don't think the cost is justified per tuning output, the BMW side would prob offer cost per performance output. If i were to tune, it would be light. I would get maybe just cosmetic and sound tunes, (ie amg mufflers) these cars are quick as is. Mercedes already engineered these cars to their potential, there is very little left to upgrade. But if ur willing to spend some $$ in chips go for it I would however tune the crap out of a e55 tho if i had the chance.
