Quoting fuel:
MotorWeek (a US video magazine) test drove the 3000GT VR-4 ahead of the Galant VR-4. Seeing how the US only got ONE generation of VR-4, and that the video was titled 'MotorWeek '91' I highly doubt they were talking about the JDM only 7G or 8G Galant VR-4s.
Yes the E39A Galant VR-4 came a long time before the 3000GT/GTO (1987 vs 1990) in the Japanese market, however for the US and Australian markets (ie the only two markets outside of Japan to even get the Galant VR-4 as a locally available model) the Galant VR-4 was released after the 3000GT VR-4.
I believe Malaysia also got some of the old 87-88 GVR4s. Didn't they?
Also, 7g and 8g VR4s were not JDM only. Germany, Britain, and other european countries got them as well. Some have even turned up here on the forum. One of which is a 7th gen with all sorts of fancy gadgetry stuck in the trunk/boot. Last i read, this was suspected to be some sort of test mule.
