Agreed, I paid a lot less for my Zed than I would if it was a uk car, it's got VSC, brembos, LSD, AC, HIDs, it's been undersealsed but no leather or jap nav!
From what people say their JDMs are equipped with on here I think it's down to an options list rather than a spec sheet? They seem to be very varied.
My only worry with them is that the millages can be fiddled with when they are imported and swapped to MPH.
