So, here's what I know.
It's a three-owner 1973 2.0L and shows 42K miles on the odometer. The owner cannot verify the low mileage, so my guess is either that it's rolled once or had the speedo replaced.
A tuneup was done about 500 miles ago that included a valve adjustment, valve cover gasket, plugs, caps, wires, all belts, most hoses, brakes (pads, calipers, lines) and wheel bearings. Owner has documentation for the tune-up, but that's about it.
Body appears to be in good but not perfect shape. I don't see any serious rust in the photos, and the owner claims no bad runs anywhere. He said that he removed the rocker panels, too, and found no rust. This was about 6 months ago, if I remember what he said correctly.
Rear driver's side fender is missing the back portion of the Porsche decal. Owner is not sure if that panel was resprayed, but claims there is no overspray indicating that it was repainted. He has another set of Porsche decals.
The vinyl on the sails is peeling on both sides. Owner has replacement vinyl he is selling with the car.
Car is at the shop right now getting a speedo gasket replaced. There was a small leak on the back, apparently.
That's about it. I've exchanged emails with the owner and talked to him on the phone. Seems like a good guy, whatever that is worth.
