One thing you should always keep in mind is that car dealerships love to try and screw you over. All sorts of shady things might happen behind closed doors, so it’s important to proceed with caution any time you go to buy a new car. If anything, just make sure to read the fine print.
A Reddit user shared the story of how their parents maliciously complied with a car dealership that refused their outside payment. But when they decided to get a car from a different dealer, the previous one came crawling back too little too late .
User justtoview2231 Shared The Story To The Malicious Compliance Subreddit.

This All Took Place About A Year Ago.

OP shares that their parents were in the market for a new car, and got preapproved for a loan from a credit union. The couple then went to a BMW dealership, who informed them that they could only purchase a car using their in-house financing. There was some back-and-forth, and the dealership eventually told the couple that they could leave if they didn’t like the policy. OP’s parents did just that and decided to go to a different dealership.
They had decided on a new make and model with a different dealership when the original dealer called them, asking if they’d changed their mind. The couple told them they decided to go with a different car, and the original dealership tried to get by telling them they could use their credit union loan instead of in-house financing. But by then, it was too late, and the BMW dealership lost out on a pretty hefty sale.
Commenters Applauded The Parents’ Actions.

Users had their own stories to share. As it turns out, there are a lot of dealerships that use similar tactics to try and get as much money out of you as possible. But as other commenters demonstrate, you don’t have to follow all of their strange rules.
The Parents Made The Right Move For Sure.

One user shared advice from their dad: “If the dealer refuses to work with you, walk out. There will be another dealer who will.” That’s exactly what OP’s parents ended up doing, and it worked wonders for them.
Users Hoped The Dealer Learned A Lesson.

Commenters pointed out that the dealer tried to set an ultimatum for the couple, but didn’t actually follow through. Hopefully, he’ll have learned a lesson.
