@Leaflord I had to buy a different car when I moved to Arizona because the car's computer was messed up. They couldn't use their emissions testing computer that plugs into the car.

I asked them what they did if the car was too old to have a computer. They said they do a tailpipe test. So I said, do a tailpipe test.

They told me if the car has a computer, they have to use the computer. They can't do a tailpipe test on a car that has a computer.

Arguing with them was futile. I had to sell the car and get a different one because I couldn't get plates.
