Hell, even us backwards, low-tech Aussies can simply mail off a cheque or pay with that internet-banking thingy! Actually, the last time I was at the DMV office, was to get the '89 registered and it was relatively painless by comparison.
I brought the car, roadworthiness certificate and proof of purchase, along with the customized plates (that are now sent out IN THE MAIL!!

) and had some gimp come out to eyeball the car. He was more interested in the car, asking me about it's power, handling and "chick-pulling" abilities.

When I told him it'd tow 900lbs of "chicks" he laughed for about 20 minutes and stamped the paperwork.
There's one legal requirement in Nevada/California that I really like: Compulsary Liability insurance. It's
optional here...

Is it a nationwide requirement, or dependant on state legislature?
