I just bought on '01. There's a steep drop-off in price in the Denver market once you fall below '02.
There's a dealer in Denver with a VERY nice gold '03 w/ Nav sitting on their lot (~70k miles). The sales guy finally got around to following up with me today and I expect they are very willing to seriously deal on their $27k'ish asking price.
It's definitely a buyer's market right now, don't wait for gas to fall back to $2/gallon
