They seem kind of expensive. This place will find out what's wrong and they will fix your car if it won't pass smog but they do charge lots of money for smog repair. A regular smog check costs the regular price but for repair work done on your car it can get expensive. Bring cash because they don't like using plastic. They weren't completely transparent about their prices. You can leave the car overnight. They have a key drop. You just have to call ahead
