He lists the car's VIN as 53563673655356385, which is nonsense. First, for a '73 Buick, the first character should be a 4, indicating Buick Division. A "5" as the first character indicates GMC truck. Then, the VIN should have three letters in it. The second character indicates the series, and for an Estate Wagon, it should be an R. The fifth character should be a letter indicating the engine, and for a Buick 455 with single exhaust should be a T. The seventh character should be a letter indicating assembly plant. Of course, he lists the car as a '76 when it's not, so the fact that he got the VIN all messed up, too, should come as no surprise.
If only it wasn't in Alaska. That would be quite a big shipping bill to ship it down here to the rest of the states.
This is the only thing holding you back on this car? I wouldn't buy it if the seller lived next door!
