How would you handle it???

So my sister has always had a problem sharing attention from my parents. It’s sad that I always feel this way. I wish I could just enjoy my sister relationship. She has two teenage boys she’s 5 years older than me. She got a divorce that same month I got engaged. She lived off my parents since then and steals from them constantly! 50-2,000 at a time. Recently too! It never has stopped. Even her boys are learning her behavior and have done it to my brother and my parents. My parents ALWAYS help her. Barely me cause “she’s a single mother with two kids” btw I have two younger boys 2&6 but I’m married so “it’s different she needs their help”

I’ve been with my husband for 15 years. I paid for my first car brand new off the lot. Every penny by me! Fast forward to now.

So me and my husband were expecting our second son. My husband bought me a new car to accommodate. My parents were broke and only had one vehicle and lived 1 hour away. Me fixing to have a baby I gave my mom my old vehicle that was in excellent condition worth $7,000. So she could help me when I have the new baby. I specifically told them they can not sell the car. If they no longer need it give it back. Also they can’t give it to my sister.

I have a scheduled c section. Everything went smoothly. My sister decides at that very moment to go with her boys on a vacation in the mountains with no cell service 12 hours away. She never saw my son till he was9 months and when I spoke about him she could never remember his name. Sad. So sad.

So my mom never was able to come when I needed her cause my sister always had the car. Cause well she needs help. Whatever. I can’t tell them how to parent. I bit my tongue. Now my mom and dad have more money. They bought two brand new cars for themselves. My dad asks if he can use the car as a trade in for my moms car. I say yes. Awesome!!

2 weeks pass. Mom has a new car. My sister calls. And says. “I don’t know why it matters but mom wanted me to include you. We are selling your old car and I was wondering if you wanted HALF of the money I will get. I’m using the money to buy me a new car. It will only be $400. So you’ll only get $200. Or can I use it all?”

It’s only been 2 years. The $7,000 car is now only worth $400?

She says she had a guy look at it. The engine is shot it was ran with no oil and the dip stick broke”

My response “sure I’ll take half” OF COURSE she was upset and questioned why I just wouldn’t give her all. I called my parents and calmly told them that why am I having to split MY CAR that I PAID FOR EVERY SINGKE PENNY OF with her?? My mom snapped back “come and get it then

So after thinking about it get this “I PAID TO TOW THE VEHICLE HERE ONKY TO START IT UP AND HEAR IT PURRRR!”

So now what do I do??? FYI I am getting it put back in my name to day! How would you go about it?

It does make a noise but nothing to value it at $400. I am having a guy look at it today. Honestly I feel like it’s the wrong oil. I don’t think my parent are trying to scam me I feel like they believe my narcissistic sisters lies that it needs to be sold.
