does anyone know a place to get reasonably priced replacement v126 door gaskets?

 

Get them from Germany. Just kidding. Here's a start

Not sure of the year of ya diesel W126 but this web site is a site. Online. Try typing in Mercedes parts as keywords and shop around. Door seals seals these cars like a vault and isn't dirt cheap.

 

ypui got the year right. that is weird they only show 3 door gaskets
