The school system needs to add a classroom a day to keep up with the growth, and they aren't. Traffic problems are overrated. The traffic is not much worse than what Chicago or Detroit or LA or even Green Bay sees. Auto registration and insurance might be higher than what you're used to back home. There's a smog certificate.
Gas is probably comparable.
Repairs seem to cost more, but that's subjective. Probably costs more to maintain a car here, but that's offset by free or valet parking most everywhere. You've got 30 days after arrival to insure your car, pass smog, get a NV driver's license, and buy plates. The cops are cracking down on non-registerers, because it's easier to deal with them with than to go solve that Tupac Shakur thing. Despite all this, you'll move here anyway.
