I'm not an expert about rust, it looks bad, really bad but I don't think it's horrible, my opinion you can easily get a year or maybe little more with this, always remember that you are on borrowed time and sell it as quick as possible if you get a decent offer.
Let's wait and see what Kajtek will see in those pics, I'd trust his judgment on this rust issue.
A year? That rust is a dream for me....that car could last more than 10 years with that level of rust if nothing is done...spray it with a little old engine oil and it'll go on for ever. The rust I have on the same components would be worse...but is not a concern.
If the rust is in the chassis and body panels then that's a different story.
