I think you’re mixing it up. Nobody actually gets 30% interest in a month. That’s the APR.

roughly speaking, your monthly interest is 1/12th of the APR.

Edit: payday loans might actually get that high tbh… but that’s a separate issue. Credit card APRs will be around 25-30% most of the time

Oh sweet. So I’m completely debt free at the moment but one of my credit cards just increased the limit and gave me 0.9% APR until March 2026. So would this be a good time for me to max it out 😬? I would easily pay it off within 6 months. I drive a Mercedes, fully paid-off, I own the title, and last month the dealership mechanic quoted me $6,000 in maintenance costs for some little issues to fix to keep it good as new. And I am so tempted to dive in and accept their quote. But I would need to use my credit card to do that. 😬 Wise? Or unwise?

The dealership mechanic is always going to recommend $6K in maintenance. I would definitely not do this unless either it’s time for them on the maintenance schedule in your owner’s manual or you’re having a problem.

In the mechanic’s defense, it’s a Mercedes.

Touche. Was probably just recommending an air filter replacement.

Or a new wiper

LOL, true story: last time I was there I wanted JUST an oil change. NOTHING else. (Because they have a propietary oil filter otherwise I would DIY it). Shoulda cost no more than $300. But the liaison lady said, “according to our records you are due for your 'Service A 'and I told her 'no I am not due for my Service A, I just had it done at a non- Mercedes dealership so that’s why it’s not in your records. All I need is an oil change right now. I do not need Schedule A.”

3 hours later they come back at me saying they did the Service A and they changed my wipers (although I literally just changed my own wipers the day before!) 😡

and they topped off all my fluids which did not need topping off because I do that myself, and they charged me for it, so what I expected to be a $300 quick trip ended up 3 hours and over $2,000. 🤦🏼‍♀️ I was livid.

So why am I sitting here contemplating giving them more money? I’m glad I posted this question here because I will listen to the advice of the Lemmy guy who suggests follow the service schedule in the owner’s manual. Don’t listen to the dealership mechanic, they will always want more money.
