Registration will probably be about $40 - $80, it's all about the value of the vehicle. It also depends on the type of plate you get. If you get a charitable plate, add that to the cost.
Your plates will cost a dollar or two.
You will have to get an emission inspection (smog check) if you live in Washoe or Clark counties ( maybe others )
There will be no inspection sticker, just a smog check.
