The '02 had 15" alloy rims that differed from the EXs, leather wasn't avail. except as a dealer installed option, had rear drums, no side air bags like EX, and non body colored rockers. Not sure if it had the fake aluminum finish on the dash and if the upholstery pattern was different.
FYI - the fifth gen Accord SEs didn't have the slightly higher hp EX engine either, and that may have been the same scenario for the 4th gen Accords. Also, and even though nobody asked, the bright red on SE coupes was unique to that trim level.
Typically, the inclusion of an SE in the Accord product line is an attempt to spur lackluster sales, and announces that a new generation Accord will be arriving in the next model year.
