I filled up my Micra for the first time today, and what a shock I got.....the vehicle had been washed and was sparkling clean when I took delivery of it....but when I opened the fuel filler door, it was awful.....it looked like someone had taken the vehicle out 4X4ing(perhaps they have)....Anyways too late in the day to do a clean up.....but that much dirt around a fuel filler cap is not a good thing. Is the Micra prone to collecting dirt and moisture in the fuel filler port?....if so, I will have to be extra careful cleaning....as this looks like it could be a prime area to rust.....
