Hmm...Well, it is old, but the mileage is so low I think that most could overlook that. Around my area (Cincinnati, Oh), most cars are fetching at least $3,000, even junky high-mileage cars. I think that the $3,500 that you were offered would be on the low end of what it is worth.
I'm sure you've already thought of this, but I'd check some of the online sites and local papers. Look for cars with around the same mileage, or same age. The rough average between them would probably be a good starting point. Additionally, if you advertise in the paper, I'd suggest putting 'low mileage ___' as the little header, rather than model year. Again, probably things you've already thought of.
ETA: most people expect to see 12-15,000 miles per year, so divide your mileage by that to find the 'actual age' of the car
