Today I did walk past another Jazz Mk.II (blue) and got so stunned that I forgot take a pic... Around the cover lid for the petrol cap the metal edge was about completely gone by rust!
I do not know the year of that one but looked like first gen Mk.II. My one is a -GG 2011 and for now have no visual signs of rust from the... outside.
This was clearly an inside job and I'm asking if any here have battled this and how to access the inside area?
Did just right of now order from fleaBay an cheap endoscope for use with your phone for future inspection..
Bottom line: Has any here gained access to the inside of that area around the filler and how?
