I think from memory they were more expensive in Japan as well.
The V35 if you take 03/04 for example, "track"version, both cars were identically spec'd, with the V35 having more options, being a larger car, with two extra seats. Why would they charge less??
Both had 18's
Both had Brembo's,
Both had the same engine
Both had the same running gear
V35 was longer so more "material" costs
