||The VG30DE design was 1985 and came out in 1986. <- I and most of the car enthusiast world is aware the design debut in the late 80s. The design cues are very similar.
The A80 Supra was designed to target the new R33 and its engine didn't come out until 1991. -> Ok, yes it's an inline 6 that offers single turbo conversion ability for ridiculous HP numbers.
The Z32 and the A80 aren't competing products and five years is a lot of time in engineering, design, and marketing years in the auto industry. -> Was it 5 years? I thought it was 3.5 to 4 difference. Either way, the world was comparing at the time and even today the RX7, 300ZX and Supra. I am guessing you are just providing some facts. Do you really think they are not in the same sports car/GT class?
