good luck with that... if it gets driven on the roads in the winter, it WILL rust. Insidious stuff...
not to dissuade you from coming here, but i would budget in a cheap rump roast winter beater for those snowy months.
that would imply you had something worth spraying to begin with..
not something easily come by locally.
Importing something rust free is also not easily done when on a very limited income.
