Those kinds of car washes are totally a thing.
 
… though normally they’re much less innocent. Or sometimes, at least.

 
^{mlfw the girls washed cars for monei is canon}

@Ryuki
 
Nuh, they decide to do a car wash to make enough money to get the animation back
 
Hence the image :D

Pour some sugar on me! In the name of love1

@G.S. 
Nice Chowder refence

@Ryuki 
LET MY PUPPETS COME route? (NSFW)

@ChuymaruZ 
A very poor joke, js.

@darknessRising24 

 
Equestria Girls R-rated ?

@G.S. 
Ok, this needs to be a story!

Pony Mane 6 are gathered around the Table of Friendship, staring with disturbed expressions at some documents
 
Twilight panicked: “Okay, no problem, I’ll just take some from the Royal Treasury…”
 
Twilight opens the Vault of Friendship to reveal… dust.
 
Twilight after a brief pause: “WE’RE OUT OF MONEY!!”
 
The others: “What? What!?”
 
Twilight, shaking Rainbow Dash: “DO YOU KNOW WHAT THIS MEANS!?”
 
Rainbow Dash: “Y-you can’t pay the peace treaty fee thing?”
 
Twilight: “No, worse than that!”
 
Pinkie: “You can’t send Spike to college??”
 
Twilight: “Even worse than that!!”
 
Applejack: “Even worse than-… I give up. What?”
 
Twilight: “No money means—”
 
the scene stops and it cuts to a scene of the Equestria Girls humans in a voice recording room together with headsets and microphones
 
Twilight: “—no animation!”
 
Pinkie: “What are we gonna do?”
 
AJ: “Go home?”
 
Twilight: “No, we are not going home. We gotta save the show!”
 
Pinkie: “But where are we gonna get the money to pay for it!?”
 
long pause
 
Twilight, having an epiphany: “Don’t worry, girls! I have an idea.”

@ChuymaruZ 
Oh okay, but’s kinda close what I thought you meant, ie that you joked, but the joke being Flash and Timber “ruin” your fanservice.

@judacris
 
ALL HAIL TEH PATRIARCHY!

@ChuymaruZ 
well, the scarcity of vehicle references and therefore creative decision to just reference Flash’s compensation vehicle to only have it washed by just the girls seemed… misogynistic.

@ChuymaruZ 
Have you forgotten that there are more girls in this series than there are men? The females need some fanservice to you know!

@BackgroundLoL  
it was a joke, because nobody want to see dudes in a car wash just girls

Someone got grime onto Flash’ Camaro.

@darknessRising24 
I think ChuymaruZ means he doesn’t want Flash and Timber in just this particular picture, but I’m not sure.

@ChuymaruZ 
Filters, they are your friends.

get out of there flash and timber!

Imminent empty pockets :P

That’s how it should be a car wash.
 
And…
