Scott,
At least we agree on one thing. Batteries. I have used Interstate batteries for at least 25 years, but I think the next one I buy I'll get from Autozone or Advanced Auto. I've heard that Interstate makes their batteries and many other brands. Someone told me that there are only two companies that make batteries.Interstate and Exide. There surely must be more. Do you know if there are more than two?
I've heard people swear that they would only have a "Mercedes" battery put in their car. Same for MB brake pads and calipers.Did you know that at one time Mercedes used Dunlop brakes? Shame.They have also used Girling and Teves(ATE). I've worked on all of them.
I won't list all the Mercedes I've owned over the years.
Let's just say I have owned a few.

After thought;none of my turbos whistle,but the one I rebuilt on the 1982 300D turbo does w(h)ine between 30-40mph
Like a minature 747 jet.Not loud. Just sweet whining.
