BNW CR Chart
This is... not even the whole list. I cut out a few that she just met once, and there are of course people who've been given lifts and stuff, and more characters that are important, but that list will just go on forever, so I put the main people with whom she's conversed with recently, or who are important to her life in general. 
DEAN WINCHESTER
The best owner in the whole world. Other cars would kill for an owner like Dean.
likedillinger
SAM WINCHESTER
The reason Dean needs to start having kids to pass his car down to. He doesn't understand the Impala in any way.
getyourownpie
CASTIEL
Total bamf and just an awesome guy overall, who's very awkward and has some issues with his life, but is very thoughtful and loves humans.
holy_hand_print
JO HARVELLE
Basically Dean's little sister who kicks ass on so many different levels.
incaution
BOBBY SINGER
A smart and cool guy who saves the boys' asses time and time again
shootdont_talk
ELLEN HARVELLE
A pretty bad-ass mom who has a lot of insight.
notyourwar
PENNY
One of the few people that doesn't deserve to get bitched at, though she needs a hobby that doesn't also count as her job.
colorcanbefound
CLAIRE BENNET
Sam's girlfriend, who shares his lack of understanding, and his disapproval.
autophoenix
BROOKE DAVIS
A former semi-girlfriend of Dean who needs to get back with him so they can have the aforementioned children.
ihadmittenson
ADAM MILLIGAN
The Winchesters' younger brother who keeps appearing and disappearing for whatever reason.
heavenwasprom
CASSIE HOLMES
A kindred spirit and fellow pranker of Sam. Their appreciation of Dean is similar as well.
farsees
CHUCK SHURLEY
Writer of Supernatural and a very rainbow-colored person who doesn't like to get involved.
endingsarehard
CLAIRE BENNET
The odd semi-copy of Sam's girlfriend who always wants to drive and had a thing for Dean at one point.
excheerleader
CAPTAIN HAMMER
That crybaby who's now become Zeus' bitch and doesn't deserve Penny.
lovingmetodeath
BECKY ROSEN
Sam's deranged fangirl who writes too much fanfiction about the boys.
lickssam
ANNA
That one angel who slept with Dean in the backseat and then put the whole family in danger. Officially on the bad list.
goneterminator
BELA TALBOT
A thief who can never be trusted ever, and who screws the Winchesters over every time she comes near them.
insilksheets
CROWLEY
A pretty cool demon-guy, when all's said and done. He needs to keep his hands off the leather interior though, and not put any more tracking devices in.
statusquodemon
GABRIEL
The one Archangel that might do some good in the world, though his methods are highly suspect and his feelings get hurt far too easily.
painhumbles
LUCIFER
The most whiny, self-centered asshole in the whole universe, with the lamest, most overused sob story ever. He needs to be run over, over and over and over until he can't take any more and just goes back to Hell.
wouldneverlie
MICHAEL
The dick that wants to make Dean into his own personal car and who needs to sit the fuck down. He lacks proper communication skills.
viceroyofheaven
RUBY
The bitch that turned Sam into the person he is today by making him hooked on drugs. She deserves to die.
leadhisarmy
REMLIEL
Yet another Archangel come down from the heavens to grace us with his irritating presence.
holyorthebroken
LOBSTER
That lobster is a demon and still needs to be sent back to Hell.
