It gets confusing sometimes.
You read through a thread thinking that you might be able to help, or that you have the same problem, only to find that it's about a different model/year. Lots of posters forget to mention what car or variant or year they are asking advice about. Some just say "C5 engine problem" for instance. That would cover about 11 years ,3 marks and several variants. There are so many different models that it could be required that the info is the first thing in any thread looking for or giving advice.
Possible or not?
