dude, that sucks. Mine had gone on the rear arches and a few bits on the bonnet from untreated stone chips, but the previous owner kept it garaged most of the time and only used it as a weekend car!
i've looked at other mx's of the same age and haven't seen 1 that doesn't have the same type of rusting on the sills. not much to worry about but better to treat it. i still cant believe it's 12 years old lol
Negative on the rust here.. not summer yet and im at 103 - 103 on some days and then constant high 90s... i love the hear.. no rust whatsoever. I do miss the rain.. only sprinkles like... once every 2 months

MX-3 w/ curved neck millenia klde, boosted @ 5 psi. /bov and wastegate are good!/ nitto drag radial/ gutted interior/ millenia red top injectors, vortech fmu/aem wideband/ all bolts ons/ Car put together 100% by me. Mechanic? who needs a mechanic? ew.. real men work on their own cars!
good luck man, at least you caught it in this stage.
u should see the underside of mine.
not only are the sills gone, but the rails are rotted too. i've got alot of work ahead of me... good thing i know some welders, otherwise it would be pretty damn costly.
Thats the only thing I like about living in North Carolina(cause I didn't always live here) is that there is so little time during the year a car would be exposed to salt. You being from England I understand that your car is constantly exposed to salt(island).
it always depends I think what year and crap with the mx3. I have owned 3 now and 2 had a [problem with rust underneath and one by the trunk and wheel wells.. depends if work was done before you got the car and what weather your car encounters...
on my car under the doors on the bottom from front well to back well is all rusted out if u touch it its like rubber lol i mean the metal is no longer hard u can flex it and put holes in it...
