Tax Time, what's your truck valued at?

[76stepsidechevy]

Well its that time of the year again and my town tax bill showed up and was way more then expected. Ive always had older vehicles and never really payed much in taxes but last year I picked up my truck and a 99 audi for the wife (got it cheap after a neighbor creamed a deere with it). They value my 76 chevy at 6020 dollars and the 99 a4 at only 3900. Im just not seeing it, I have an 85 buick regal and when regged in the past its never been valued more than 1000 dollars. I think Id have a hard time selling my truck even at half of what they value it. Am I crazy here or what?
