Hello dear Mercedes experts, I saved some money together and would like to buy my first classic. I really like the W123 and it reminds me of my youth time. Actually I thought that I want to buy a & cylinder, however these vehicles seem to be really rare, on mobile I found only 2. Can someone help me a little about the engines, years of construction and weak points. Are the 6 cylinders much more popular and therefore so rare and thus also significantly more expensive? Which purchase price must be planned for a good vehicle? Many questions at once, I know:-) Thank you for the help
