@Markos,
I emailed him through the CraigsList system yesterday with questions. No response yet. No phone number contact in the listing or I would have called him. One problem with the CraigsList email system is that responses often go to the seller's unchecked spam folder. Hopefully that didn't happen this time and the seller is just too busy right now to respond.
I am on the hunt for another project. It's starting to feel like "Groundhog's Day" to me now without a car to work on and car projects to solve.
To me, it does look like rust perforations at the belt line trim on the right quarter/deck lid, and rot at the front of the right rocker and door. If that is the case, I would suspect much more. I do not do rusty cars. I don't have good enough welding skills, you never get it all, and you end up with a patched car. I am too spoiled here on the West Coast with too many rust free or nearly rust free cars to choose from to take on a rusty one. Rusty (too a point) works for a car with the value of an E9...especially if the restorer has good MIG skills and experience.
It is a relatively short drive for me (2 hours) and worth checking out if the seller responds.
