There are so many typos and mistakes in that add, it makes the seller look incompetent.

"Pressure Plat"
"Torque Trust" wheels

Cheap generic tires
No mention of the type of 4 speed manual nor a mention of what year the 2bbl 351W is (why use a 2bbl carb on this engine?)
The seller doesn't appear to know the rear axle ratio, only describing the gearing as "good".

To me this looks like a car that was put together to look from the outside first, and everything else was secondary. I don't think the person selling it is knowledgeable about this specific car or cars in general, as he/she didn't bother to do any research on the year of the engine, or the actual type of transmission the car has. To me if I'm buying a car like this, I want to know every detail about it, I want to know what year the engine is as some years the 351W had 330 HP and some years it had 150HP. I want to know it has a top loader 4 speed or an SROD 4 speed. I also want to know what the axle ratio is. Since this seller didn't mention any of that, I'm guessing that they are just an outfit that flips cars and doesn't actually do much in the way of mechanical work or even bother to do any research on the cars they are flipping.
