I have a lot of experience with Korean Skylines, Indonesian ones, and the USA line. The very early year 2002-2004 are the best years hands down. They were handled pretty much just like the USA line and were fully worked by the USA techs including the electronics being installed and all fretwork. They weren't just inspected. Once production went up my theory is that the techs had a harder time keeping up and I think the sketchiest period is the late era Koreans. 2005-2007. The Indonesian ones were a marked improvement over those especially when the PLEK was brought in. So are the Korean ones better? Not all of them but the 02-04 ones are the closest to a USA Lakland that I ever saw a Skyline get. Not all 05-07 are bad either but if I had to buy blind I would take an Indonesian one over one of them. The Indonesian ones tend to be on the heavier side when compared to the Korean ones.
