Thank you for the replies, don't know what to do about the inner wing yet, full extent will only be visible I guess once everything is removed, but that will be an MOT failure due to structural.
Will probably have to do something similar to this person,

But im gathering now how common this car is for rust in this spot, which is why availability of 2nd hand parts is slim.
I pulled up left hand side carpet, couldn't get it up completely to see whole side, but pulled back the corner and it looked pretty clean, paint still shiny read and no signs of rust... but could be further back and on the wheel arch, cant see that.
Wheel inner arch for that side is still available by looks of things from Alfa, albeit for a fee...
Managed to track down 1 new genuine rear quarter panel hopefully, old stock, but only for passenger side.. still need to find one for drivers side.
Going to be expensive to get back on the road by the time ive done the engine as well!
But worth it I think,
Alfa Romeo 155
According to that page, the 2.0 TS Lusso (if im correct with model) only 217 was sold in the UK.
ALFA ROMEO 155 TWIN SPARK LUSSO - How Many Left?
theres only 5 left on the road and 6 sorn (1 of which is this one)
So it would be a crime to scrap it.
