Hi I am the owner of a grey market 450 the was previously registered in WA. I am trying to register it in CA but am being required to have it tested and certified to meet CA epa compliance requirements. It is a G&K converted vehicle and only meets federal emission compliance. My question is, is there anything different on a 49 state legal smart 450 than a 50 state legal smart? Or is it only the fact that the testing was done. G&K wants $2500 to fonvert the car but does it really need anything converted or just a test done?
