It depends on your local club and what their benefits are, but besides the longer towing (for us basic membership gets you to the nearest AAA garage or 3 miles to any other location, plus gets us 100 miles), there are differences in some of the other benefits. Free passport photos, higher amount paid for a locksmith, free gas if you run out (regular members have to pay for the gas) etc.

Some clubs have a Premier level above plus with even higher benefits.
