The rusted through cowl at the cowl vent is a big problem. That is very hard to fix, and it is the cause of the rest of the rust inside of the cab. Gauges might be rusted badly and not rebuildable.
I would not offer $5,000 for that reason alone.
Take a closer look at it and make mental notes with your nit picking glasses on. Don't allow your emotion to get the best of you.
