My gas car registration fees in Seattle are $160/year total. Of that either $80 or $120 is flat by weight and the remainder scales by value. If your fees are $500/year, your vehicle is extremely heavy, expensive, or both.
It's kind of funny, because from my perspective I'm an old man who learned himself a trade decades ago and worked things right to the point that I don't have to drive around a shit-box anymore, but to you I'm a privileged asshole. Which one is the truth?
