look what I found , I didn't know zeds came with allotments.
Jacked through
Anyways good news is it's only rusted through a small patch which should be easily weldable
However I noticed water must have ingressed through to accelerator pedal mounting area making the metal soft ,again another patch will be required
Got me thinking though that this is not an obvious place visually for muck to build up and if z3 sills have been on a few years might be worth checking out. Just a thought
Anyway will endeavour at my own pace and maybe one day will get her back to an acceptable standard
