Arizona Vehicle License Tax

[PHX ATC]

All right, does anybody know how this crap works? I've been here 19 years and really haven't been bothered to figure it out.
We're contemplating buying a used car that had a sticker in 2002 of $49,000ish. That's without options (usually how AZ works it, I think). How in the heck do they get their VLT out of that? How would it figure down to a 2005 registration fee based on that information?
Basically we're trying to figure out how much our registration would cost for this used 2002 auto before we buy it.
Thanks.

This is from their site. I am always buying and selling something so you think I'd know this stuff :)
It varies depending on the vehicle. There is a $4.00 title fee; an $8.00 registration fee; plus an air quality research fee of $1.50; and a vehicle license tax (VLT) assessed in place of a personal property tax charged by other states. There may also be a weight fee for commercial vehicles and other fees. The VLT is based on an assessed value of 60% of the manufacturer's base retail price reduced by 16.25% for each year since the vehicle was first registered in Arizona (15% before 8/1/98). Then, as of the Dec 1, 2000 reduction, the rate is calculated as $2.80 (new vehicles)/$2.89 (used vehicles) for each $100 of the assessed value. For example, for a new vehicle that costs $25,000, the first year assessed value would be $15,000 and the VLT would be $420.00. The second year the assessed value would be $12,562.50 and the VLT would be $363.06.
BTW: They use the NADA guide for values see nada.com. donat add for anything including mileage to get their figure.
I would call them MVD 602-255-0072. My new Avalanche stickered at 39K and was around $730 for the first year tag.
Also inked a deal on a new Lavey if you saw the thread. :D
