Just got a 91 300SE and have noticed a sort of rumbling noise when under medium or greater acceleration. It's particularly noticeable during left turns. I've not done a complete check of the exhaust system to see if something's a bit loose (I should be so lucky). If it's not something as simple as that, I'm hopeful that someone here has experience with the same sort of thing and can offer some advice as to what I should look for.
Thanks!
