Ok guys... I really dont know the point of this post, so just bare with me... two summers ago I was given a car by my grandparents, a Toyota Highlander... at the beginning of last summer I was led to believe that at the end of that summer I could trade it in for a sports car... well that didn't happen, so I made a deal with my parents that if I kept my grades good this year (senior in HS) that towards the end of this year I could trade my car in as long as I could afford it and insurance wouldn't be any more... well heres the deal: in EVERY disagreement my parents and I have, they always pull the card saying I can't trade in my car, even though they didnt pay for it... its really starting to piss me off

... tonight I told my mom I didnt want people over at my house much any more because last time they came over it was too much hassle getting ready 4 hours for a 5 hour party... just not worth it... well she gets all mad and says forget the car, im so pissed off right now

... Ive fulfilled all the requirments of our agreement with a 3.6GPA and still they keep saying no to what I want (sc300), even though it wouldnt cost them a dime... anyone else have issues like this with their parents, and how did they deal with them? Im getting so fed up im about ready to just take myself out of this house...
ps- no im not a rich spoiled brat by any means, I just believe that when an agreement is made by two parties and one party holds up to their end of the deal that the other should as well, and I cant supercede my parents because well, they pay my tuition etc... I will NOT be this way towards my kids, it depresses me and makes me lose all faith in them as parents and as people
