This 1977 Toyota Carina commercial shows how the A40 Carina was designed: with tron-like neon computer vectors the laser sharp lines of the A40 were cut out and moulded into the famous (pre-facelift) shape!
Apparently Toyota did not need Sonny Chiba to convince us the sharp lines were the way to go in 1977! Did they they change their mind and rehired him in 1979?
