I've owned a 2nd-gen Camaro Z28 & a TransAm, and a couple E-body Barracudas/Cudas (1 each).
Similar in functions, even in some of the styling, but different of course in the execution.
The Cudas had arguably better basic engineering, but the Z28 was better-assembled.
The Z28 felt lighter on its feet, so to speak, but that could be powertrain differences between the two I had.
Wish I still had them.
