Owning a car in Pennsylvania is the hardest thing to do. Registration costs, their ridiculous registration notaries, and their own private fees - it’s outrageous.
You buy a used car in PA and it will cost you $600+ just to register the stinking thing. It makes poor people worse off because they can’t ever get to work.
In AZ, we have to pay registration fees each year based on how old/new the car is. That can add up to several hundred dollars if the car is newer. On top of that, there’s emissions testing/fees. The emission testing is every other year.
