Had him hold the order to try for another at half price shipping. It is on it's way now. He claims they have been installed in mercedes for the last fifteen years.
Cylinder is plastic unfortunatly yet probably okay. I just preffer glass as it does not yellow with age and heat.
I still think the vendor is okay. I believe he might have read this thread as well. As he also told me the cylinder portion was plastic without me asking. I cannot remember asking anyways.
Will still report on it as soon as it arrives. Should be in the next week or so.
