$15k-$20k to spend - which used Subaru?

If you have $20k to spend, buy new. You know the history of the car and you get a warantee. My 2003 Baja was a left-over that had arrived at the dealership in late 2003 after the 2004s were in and didn't sell. I bought in the fall of 2004 for $17,950 with 10 miles on it. I purchased my 2004 Outback when the dealer was advertising $49 over invoice minus holdbacks, and there was a $1500 factory rebate on top of that! The car cost under $21k before tax and license.
