Is there any benfit to list the category on some second and third generation (1974-1993) Ford Mustangs as "Hatchback"? Most are already classified as coupe, which I would think is more appropriate, but there are a handful categorized as hatchbacks. http://www.imcdb.org/vehicles.php?resultsStyle=asImages&makeMatch=2&make=&modelMatch=- 1&model=mustang&modelInclModel=on&modelInclChassis=on&class10=10
Would it be correct to consider them more of a liftback or fastback even though the rear glass window does lift open with a function similar to hatchback?
There was a discussion here: http://www.imcdb.org/vehicle_4595-Ford-Mustang-1990.html

Doesn't hatchback imply a car with more of the shape like these with a more nearly vertical rear window? http://www.imcdb.org/vehicle_56587-Honda-Civic-1984.html or http://www.imcdb.org/vehicle_42646-Volkswagen-Golf-Typ-1J.html

Also, the 1982 Collector Edition Corvette and all C4 Corvettes have a rear glass hatch which opens also, but those should definitely be classified as coupes, right?
