Peddle or Junk my Car sell junk car vehicle truck Nationwide

My 2000 Toyota Camry was well taken care of for 15 years and in excellent shape but the water pump went and the engine died. I had no idea how much it was worth so I went on Peddle.com and put all of the information in about my car. The site said if I wanted to sell it immediately I could get around $300 and if I wanted to wait two weeks I may get around $600 but I did not want to even list it for this lowball offer and there were no other options to list it on that site for higher. I listed it for $1000 OBO on CraigsList.org thinking it wasn't worth much, per Peddle.com. The first caller offered $1000 without seeing it but could not come get it for a week. The next person came to see it that night and offered $1000 so I accepted right then. I called the first person back to tell him it was sold he said it was probably worth $1500-$2000. Peddle.com added salt to the wound by sending another email and said they increased their offer to $1700. If you don't want any money for your vehicle go to Peddle.com for a LOWBALL offer otherwise find out how much it is really worth somewhere else and sell it on Craigslist.org! Please learn from my $500-$1000 mistake and avoid Peddle!
