This is an internet forum. Not some automated response site
When people want answers to their questions, they usually make specific topics on that question, or do a search to see if it's been answered before. If you're having problems with, say, a 560SEL stalling, you can type "560SEL stalling" in the search box and immediatley find threads about this issue. Or you can post a new topic saying "'89 560SEL stalling" and then go into further detail in it.
Not only did Mercedes have MANY different models over the years, but many of them shared common engines, transmissions, and chassis. Did you know that a 1985 300SD - with a diesel engine - had the same chassis (126) as a 1983 380SEL... and a 1991 560SEL? So if a window regulator is broken on someone's car, they can ask about 126 window regulator replacement and have their questions answered by any of the hundreds (thousands?) of people on these forums who own 126-chassis cars - such as Mike!
