Build date May 2012 - was almost guaranteed I'd be suffering from the rusty seat problem
Does some rust on an internal surface matter to me? In a word...
yes! Our UK climate seems to be getting wetter which means more humidity and condensation inside the car (only have to watch your windows fog up as soon as the a/c/ is off these days). Given that rust is porous, the condition of the bottom of the seats will only deteriorate over time. I'd also say it's safe to assume
both sides of the metal are rusting. Who knows, maybe the seat backs are rusting away as well under the fabric/leather?
Maybe I'd expect this on a budget far eastern car that's a few years old, but not on an six month old F30
