100k miles with timing belt just done and fresh paint, you could fetch $3500 reasonably on the open market. You COULD be like all the dick dealerships and upcharge the accord to $5000+. One of my friends went looking at a 1995 EX sedan that had 175k miles and the dealership wanted $4900, and the car looked like shit. People are going ape shit from 4-bangers right now, just mention in the ad what your gas mileage has been and people will call you like crazy...
random question, how much did the paint cost you, did you use OEM (dealership paint) or did you use aftermarket matched closely to dealership paint?
