pecel - This question was asked recently (cannot locate thread) and a forum member said he was able to rent a car even though he was under 21. It seems only local car rental places (not national) will do this and it costs more than it would a 25 year old. If you are 21 or older Enterprise will rent to you. Look in your local Yellow Pages phone book and you'll have to call around. Seattle, WA to Vancouver, WA is probably ok but I highly doubt they'll let you drive from Seattle, WA to Vancouver, BC since it's outside of the USA.
