Its so weird to see micras like that.
I havent seen a single K11 in aus with rust in the sills. heh.
Rust in the front lower radiator support is common, rust in the doors I have seen, rust behind the front quarter panels/firewall where leaf litter builds up inside the guard, rust around the rear window rubbers, rust in the sunroof pressings. Thats about the most I've ever seen.
Curse your road salt hey!
