please help

Me and my mom just got into an arguement while i was working on the mustang because she said thats all i care about and i do nothing for her but everything for the d**n car. so she is putting it on craigslist and auto trader to sell it she doesnt want me around the car anymore. That car is my love Is my life. she kept it because i told her i was leaving the house if she does. everytime i say MY car she yells its hers to correct me and yet she hasnt literally touched it in 2 years. an even after her correcting me she comes down stairs and tells me to read the title and read the specs when i am done with it i hand it to her and she tell me to keep it? she is freaking torturing me. i rather be grounded. from everything except her. i have talk to at least thirty people and everytime i get the same response. "If it was my car and you took that much care of it, i would have past it down to you." i have been trying to sell my truck for some time now by=ut have not been pushing it.

Now i need some serious help.
i need the truck gone. now. so i can give her at least 2000 and 500 to fix the car otherwise its gone.....i don't think i can handle that... i just need money down to prove to her i will buy it. it WILL be mine.

Imagine someone driving you dream car. bragging. teasing you that it could have been yours easily..

i dont know what to do. im to young to understand i think.
