They are in the business to make money... cannot fault them for that...
Crumb's Bro,
I look for cars that changed models :) ... as you said once the "new" models hit the used car lots the older models dump in price. We purchased my wifes car that way (picked it up 3 years old, and a new body style came the year after her model... at any rate it was a nice car with about 28k miles on it. We purchased it for under half the original price).
I'm hoping this trend continues... I have my eye on the "old" BMW 540. The "new" body style came out in 2004. I'm hoping I can get a 2003 two years from now at a nice discount... we'll see...
