There are people, like me, who's facing crazy problems with their car..... then you've got other people who buy and sell cars just 'cuz they want to. 

Oh how easy it must be for him. He's got multiple cars, so what's it to him if he sells one... right? And it doesn't matter to him that he had goals for US to learn/relearn driving stick. Well, he's had his practice while I got very little - so for him that means he can sell the car because IT'S HIS AND HE BOUGHT IT and I have absolutely no say in this matter because I had no financial contribution towards it.

Whatever. There goes my chances of mastering stick. And there he goes never being satisfied with whatever vehicle(s) he has.
