"Illinois has high property tax, but doesn't it still cost less than $100 to register a 2021 Lamborghini?"

Hahahaha!! I would not know what a '21 Lambo would be. But we'd get smoked in sales tax on that kind of purchase. But your point is taken. I believe our registration is $151/year.

Illinois is creeping up there. Our general sales tax rate is 6.5 and then increases based on county and municipality. The R/E tax is fairly high in throughout the suburbs of Chicago and I'd be willing to guess our income taxes are about average to the rest of the country.
