Is there a "Asakura Tax" because of the Fairlady 240Z in Wangan Midnight?? That cartoon started in the early 90's too, but people considered the S30 a classic long before that... it remains a nostalgic hero today along with other models, like the Hakosuka Skyline, TE27 Trueno and Levin, Datsun 510, Mazda R100, RX2, RX3.
The AE86 is already 25 years old and will be revered as highly if not more so than other cars of similar vintage.
