Shipping is expensive these days, and you have to figure, while a few got by with a few loopholes, and were street plated in California, many of them were not and were only considered 'green stickered' for off-roading (green-stickered means you can ride an off-road bike year round in California on off-road areas).
I do believe many people in California are 'snobs' so they look down on Chinese bikes (of course, not all since we have California members, but enough that these are looked at like they were in 2005). If you peruse the L.A. or pretty much any California metropolitan area's Craiglist, you will find plenty of perfectly good, intact, GY200 endures of various brands selling for $400 to $500 and that is after being weeks on Craigslist.
