New to the citroen community

Hi! I am new to both reddit and hopefully soon new to the citroen community aswell.

I am currently looking into buying what I can only describe as a very good looking Citroen BX. But I am not really familiar with these models or any type of citroen really so I thought who better to ask than the lovely people of this sub? If there is anyone here who has some good information about BXs and common issues and other things to look out for when buying one I would appreciate any help.
