Want one so bad.
A coworker of mine has a 2003 with 14,000 miles on it in great shape (the paint leaves a little to be desired) that he really wants to sell me, and I really want to buy it. We haven't talked price, but KBB really inflates its value thanks to the low mileage. Last year of the AP1, which has its appeal.
I recently picked up a first year model, 2000 with only 13k miles. As you can imagine, mint, 1 owner, never modified, even still has the original tires which need replacing asap.
I'd say just pick up the best condition S2000 you can find.
