Am I the only one that does not see a value here. In my opinion it is not worth half the asking price. You are getting a bare bones Mach1 with nothing special. I do not think the Decor Group lower side molding was available on a Mach 1 so was added. The higher trim is aftermarket for sure. It is not a restored car just a car that needs everything. With the engine with that many miles the valve guide seals are crumbling and just a matter of time until the oil pump locks up from a piece of the rubber being sucked in. Or the by pass valve on the oil pump stick and it explodes oil filter. I would say if you went and did an up close inspection there will be rust issues in cowl and tail light panel, always there. Just washing these cars rusts them out don't have to be in salt.
There are much better cars that come across eBay all the time. I had to quit looking to keep from buying.
So if you bought the car for $15,000 and put $20,000 into a correct restore doing lots of work yourself it would maybe worth $22,000. Nothing special to draw a big money buyer.
That is how I see this car, just my opinion.
