Wow thanks AlBags for your very informative answer. You learn something new everyday!
Please would you be able to give me an idea of which wheels to look for, which will be compatable with my A Class, many thanks.
I looked through my PCD list ... and I can't find anything.
Ones with the right PCD and offset have a hole too small.
Only chance will be any Mercedes wheel .. or aftermarket MADE to fit Mercedes.
