I sold my 05 with 80k miles 4 years ago for $6k. Now I'm seeing over 100k miles cars selling for between $6k and $9k. Hard for me to pull the trigger on another srt for what I sold mine for being 4 years later and higher miles. Was hoping to see one traded in at the automotive group I work for as they usually only trade for 2k to 4k range. Just have to keep looking.
Unless your car was beat up, highly customized, or shottily modified (cut wires, cut metal) sounds like you gave someone a deal. I would have easily bought a mint stock 05 w/ 80k for 6 grand.
