I think it is okay to include 4 seaters as sports cars, but they must be originally have been marketed as a high performance car. I would include the mustan, viper, corvette camaro/firebird and such, though the early mustangs were not performance cars from what i understand.
the 300M. no no no no. why, i just don't like it.
some things i know
the mustang was originally built using the ford falcon chassis
supposedly mustang was originally named after the p51 but the association with a type of horse stuck, i think.
there was a 2 seat mustan show car that predated the introduction of the car.
the first production mustang was a 64 1/2 model
the mustang sold around 400,000 copies in it's furst 1-3 years, or something
the major shelby cobras are the gt350, gt350 r, gt500 and gt500kr for king of the road. i believe the non kr model is said to be better.
there have also been mach mustangs and boss mustangs, mach 1 boss 302. i think the late larry shinoda was involved with one or both of these models. there were at least other machs, not sure about boss 302s
larry shinoda was behind the 63 corvette stingray
there are two ways of spelling stingray. stingray and sting ray, depends on the model, don't know which goes where.
the first corvette of '53 used the blue flame 6 engine
there was an anniversary edition of the corvette in 93 or 95 that was painted in a special ruby red or burgandy, i think burgandy, paint to mark it's 40th anniversary
the zr1 is something i know little about, but i think it was introduced in 1988 or 89
during parts of the 80s mustangs out performed f bodies
the camaro was at one time going to be possibly called the panther.
the name cougar may have a connection with the fbodies?
in 73 the trans am sd 455 was one of the few true performance cars available
in 89, using a buick turbo v6, the 20th ann. T/A was faster than the corvette. indeed, the trans am even out did the vette during some years in the 70s
SS stands for super sport: camaro
rs stands for rally sport: camaro
h.o. stands for high output: firebird
firebirds came in the esprit, formula and trans am, maybe others.
the trans am was introduced in 1969
the 73 sd 455 did mid 13s and 0-60 times under 6 seconds
the gran sport corvette was introduced in 1996
reeves callaway has been building special cars based on the vette and modifying vettes for years, one special vette being the near 255 mph sledgehammer
john lingenfelter is also a famous tuner
i'll continue shortly
