Such a new car? Focus st mk2 starts 55 plate.....8 years old now.
Rust is down to how its looked after and treated to be honest. I had an x plate old mk3 xr3 that was mint 1 owner from new was looked after had not one cm of rust because it was looked after. Stuck it next to another one and you would think it was brand new.
Thing is today people dont look after stuff because if finance and things like that. They just think well ill trade it in in 3 years so whats it matter sod polishing it.
Broke 2002 plate audi tts and 51 plate ibizas with more rust in them than an old xr3 lol yet my x reg
ibiza had no rust because it was looked after. Yes these are older cars but still my point is look after them they wont rust. No rust on my 07 plate st3.
