my 96 Civic has 240,000 miles and its bluebook is well over $2,000. I wouldn't sell it for twice that since its been so reliable.
I think with any car you buy, its history, maintenance and condition trump mileage.
I research any model I buy just to make sure that it doesn't have a crappy resale and build issues. MSN autos has been my friend in the past with that with owner reviews and model details.
