Technically I didn't poke it first, the MOT tester poked it first, then I took it home and poked it all the way back to solid metal. Next will come sanding, then grinding and then welding...
I concur on Mazda 3 and their rust issues, there is one in the car park at work that has a fist sized hole in the front wing and the metal around it would probably give way in a stiff breeze. There are very few newish cars that can rival it for rusting I'm sure...
How old is the Mazda 3?
