those prices way too high. for 2000 one buying price should be $17,000-$18,000, 1998 should be $13,500-$14,500.
check this out for pricing ->

BTW, next generation of Accords is due this September, so may be you should hold on for a while to see how 7gen will look like.
another thing, since you're looking for coupe, 7gen Accord 2dr will be more sportier (it suppose to fill empty spot that Prelude leaves open on market)
