CarFax License Plate Searcher 9000
Raw
carfax_plate_search.rb
#
# Ridiculously basic script to search license plate combinations.
# I removed the user-agent and cookie headers that I copied from
# chrome, but if you need them just add your own user-agent and
# cookie from the carfax site back in.
#
# You'll need to change the possibilites, plate pattern and regex
# to suite your needs. I wrote this in about 5 minutes so it's
# basic, crude and pretty unmaintainable, but gives you a sense
# of what can be done.
