I'm looking for this fic and I can't remember the title of it so any help would be appreciated.

Things I remember:

- Sam and Dean are in the Impala, they're both still in High School, I think, and they see a hand come out of the trunk of the car in front. The girl inside had poked out the rear light and had stuck her hand through.

- Dean had Sam call the police while they followed the car and the Impala crashed, before Dean could tell the police the number of the license plate number and Dean lost his memory of the crash.

- John got the call from the police and he found out that his sons were hailed as heroes by the whole town as the recording of the phone call to the police was broadcast on the news and radio. I remember John was very proud of his boys.

- Dean, Sam and John went with the police to reconstruct the accident in the hopes that it would jog Dean's memory.

- The girl inside the trunk was rescued, insisting that there was someone in the trunk with her and she invited Sam and Dean to a party to thank them. She found out about them hunting and she helped them do research into who her kidnapper was.

- The car belonged to a murderer who had kidnapped and murdered various girls before selling it on to the would be kidnapper.

Thank you in advance.

EDIT: Found! It's called It's Less Traveled By by Mirrordance Thanks to the awesome heavenli24 who found it.
