318 power!

$416.00 is cheap. Here in Missouri you have to pay sales tax,which i think is like 7% for motor vehicles plus a $14.50 title fee and the plates are based on title horsepower. When I bought my 2019 Colorado it cost me somewhere around $1500.00.
Well it was only that "cheap" because I bought a 20 yo Durango. If it was 10 yo or less and/or if it was "worth"$15k+ those fees SKYROCKET.
Part of that $416 was a dept of revenue "use tax" which in my case was $100 of that .. which is the cheapest it can possibly be anymore. That is the part that skyrockets for a newer vehicle.
I know a guy who bought a newer charger at an auction, it needed some bodywork so he got a deal on it. He went and registered it, and some time later gets a letter that they "audited" his application and by their estimate a 2016ish charger is worth much more than he declared as having paid for it and demanded the difference in "use tax" between what he initially paid and their estimate.
Now wait a freaking minute. The DMV (which in IL is under the secretary of state) that is who runs license and title. When I go in and get pissed at what they charge I am reminded that this is "permission to have it on the roads in this state"
Isn't that the very definition of "use tax"?
Then why/how in the world can the dept of revenue add additional "use" taxes? That seems unconstitutional to me. A tax upon a tax.
This is unconscionable. Whoever comes up with this BS should have to rot in a prison cell. If this isn't criminal then I guess I don't know what is.
