there are 4 on cars.com right now, but I would be lary of the NE
There was one in the south fo $17.5K when I was looking that sold
They are there, just have to be patient
They're either rustbelt or NE vehicles. One is at 216k (and priced high for those miles). The one at 127k and $19.9k is probably a good deal. The one at 84k and $18.9k is either the deal of the century or it's a salvage title with rust.
I guess I should qualify my previous statement: out West (OR/WA/CA/UT/NV/AZ) you won't find a sub-100k 2003 below $20k, at least not easily. The majority that I see - and I look frequently - are in the $22-23k range if private or $25-26k if at a dealer.
