I can't speak for AZ but here in CT cars 25 years old or older don't have to go through emissions testing anymore.
If you sell a car in Sept. and it is smogged until DEC. of that year, are you responsible for the smogging?
The past tense is smogged.
Look for a blown fuse.
You don't need to have a 1948 car. But they are tax exempt, you do not need to get them smogged. They are worth a bunch of money. They are very neat. A collectors item even if they are not in that good of shape.
In most states if your bill of sale says "sold as is" you have smogged the buyer. It's a good idea to keep a signed copy of the bill of sale also. Some buyers never put the car in their name. You may get later get parking tickets and even be sued when the buyer wrecks someone else.
It's exempt
Typically at renewal of the vehicle's registration.
yes
you pay tax for the state in which you will be registering it.
No, after the first 3 years of a car it needs to be smogged to register the car. I think the only exception to this is hybrid models. I have a hybrid that is 6 years old and never had been required to have a smog done.
Yes he did
get more straps
