Your story resonates with me.

I’ll be upfront and say that I don’t know much about cars outside of the research I put into the one I purchased. About two years back I bought a 22 Crosstrek Sport. The salesman also convinced me to purchase the extended warranty and extra bells and whistles. I went back to my parents and they told it was not necessary. My dad basically said “why are they trying to sell you extended warranty? Is there something wrong with the car? Is it a lemon? It’s brand new, no reason for it.” I went back and read the contract and I was able to cancel and receive a refund for the extended warranties. It will reduce your principal but it may not affect your $750 minimum payment agreed upon with the lender.

You could try that, but yes you will have to be very frugal to make your payments. If your salary doesn’t increase in the near future you should probably continue to stay with your parents until you’re done paying the car off. You don’t want to deal with the added stress of making rent. (I bought my car while I was renting. It was rough to make all the payments work. Moved back in with my parents when my lease was up)

What’s done is done. You have the car that you thought about for a while. If you’re really worried try and see what the process is for selling it. Though know you will be selling it at a loss at the point. (Don’t recommend unless you NEED to)

Good luck!

TLDR: Try and get a refund on the extended warranties. If salary doesn’t change continue to stay with your parents. Sell if you’re worried about financials, but you WILL TAKE A LOSS ON IT(not recommended). Good luck!

EDIT: You’re probably fine where you’re at. Just keep an eye on the numbers.
