The picture is a 1968 Mustang
Coupe with some add on Shelby Mustang trim and a body kit. There is no such model as a Cobra in 1970 except the 1969 / 70 Shelby that was a fastback of convertible. In 1970 there was the Boss 302, Mach1 and your basic Mustang Fastback, coupe, convertible. You could get the optional 428 or 429 Super Cobra Jet SCJ or CJ motors, but no Cobra Mustangs. There was a 1976 Mustang
Cobra that was a sad try at trying to bring back the muscle car Mustang.
Any car you buy depends on condition and how well you maintain it.
