I agree, it's their car and their money. At the end of the day you'd have to be a loser yourself to go out of your way to "put them to shame". I mean WOW, you have really effecting the world we live in and improved our quality of life and health *eyes roll*. Actually I LIKE people who do that, not everyone can afford to own and run an AMG but want a head turning car, it's still a Mercedes. By the way according to what you're saying Renntech and such should not badge their cars AMG if they've made severe modifications, I mean just because the car started life as an AMG (which it didn't) it shouldn't get to keep that badge if not stock. A W211 E55 shares the chassis with the W211 E500, sure suspension, sways, brakes etc are different but the barebone car is the same.
I look, I turn away, I mind my own business.
