After the rust problems seem to be widespread in the M6, unfortunately the M3 is also affected by the brown plague. It seems that mainly axle parts/carriage/carriage are affected. Unfortunately, my M3 was no exception, as you can see from the attached picture. So the M3 looked after only 1.5 years (!!!). My Mazda dealer removed the rust and repainted it. At first, however, they wanted to get rid of me (does nothing, quite normal, good thick steel, it does not rust through, etc. etc.). Finally, however, it was done, and this is because the rusting guarantee does not apply. It applies only to rusting (was not rusted yet), only to the body (carriage parts do not belong to the body), and only to rusting from the inside (not outside, as with me). In other words, the 12-year rusting guarantee is pretty much for the garbage, especially since you have to have all inspections done at the Mazda dealer – and only at the Mazda dealer – always and on time. ss, otherwise she’ll disappear. It’s a pity that the quality of Mazda’s now going to be fluted…
