Thanks for all the advice,guys. I will try a diifferent alignment shop, I have always been a little suspect about the Sears I went to in Warner Robins. See if I can find a shop familiar with Mercedes. The car has 207,000 miles and the steering shock was replaced recently along with new Bilstein struts all round.
As for slowing down, you are right Steve. You better be keeping a good rate of knots up especially on I-75 or I-285 in Atlanta which is part of my daily commute to work or you will be driven off the road even in a Mercedes!
I'm sure it's necessary to crawl around Seattle with all the rain they have, but not here in sunny Georgia.
Anyway, I am afflicted with Lead Foot Disease which in my case is incurable!
Later y'all,
Colin
