Timing belt is covered, so there would be some work involved in inspecting that. Not sure if the owner would necessarily trust you with such a task. Might just want to take it to a dealer/independent to have the vehicle inspected pre-purchase for any flaws.
Del Sol is a 2 seater, don't know how that fits into your carpooling equation.
My Civic came from the CA coastline and has quite a bit of surface rust, I would imagine this would be even worse where it is prone to snow.
Rust was found in the rear hatch area and on the bottoms of the doors.
