A 2001 Prelude with 20,000 miles. Blue Book rates that at $19,500. I'd try to get it under $19,000, but you may have a tough time (limited production, don't make them any more). I've seen 2000 Preludes go for $18,000, so this is a car you definitely buy because you want it, not because its a good deal. Production for U.S. Preludes in 2001 was under 14,000 total, including Type SH.
Prelude99 -- You could get leather installed at the dealer when new, and I beleive my dealer wanted 1800 dollars. They actually remove the factory seat fabric and re-cover the seats. I didn't want it, though. Too hot in summer, cold in winter.
