At the time of the movie though, all the Leroy types were fawning over it cause the JDM was too mainstream
Safe to say a combination of rarity / collectable and those movies are responsible for JDM sky high prices. No surprise that the vehicles with the most gained from it are those featured as heroes in the movie...34R, Supra and RX-7. S2000 has also seen a good comeback on pricing. Then again, Jap classics like Hakosuka, RX3, VL Commodore and 2000GT did it just fine without movie power behind them.
