2003 Subaru Forester issues: Should I cut my losses and get a different vehicle?

The early Ford Focus 2.0's were belt but they were non-interference. But after 2005 they switched over to chain. The Hyundais use belts and its an interference engine that self destructs. There's a Hyundai/Kia plant not far from here. They also use a soy based wiring that is favored by rodents. But I still see a lot of Kia's/Hyundai's around here.
There is a company that's advertised on the CarDoctor radio show that's called New Hampshire Oil Undercoating that sells a product that inhibits corrosion. Probably just used motor oil.
As I understand it, the first thing to corrode thru are the aluminum brake lines. So be careful.
