grammar fail... hard to understand. That post was the longest sentence I've ever seen in my life. Looked a lot like a paragraph... yet only had one full stop. Confusing.
So you've been given 15K, and they bought it for 15K, and you want to buy it back for more than 15K? I think that's what you were trying to say.
What happens if they don't want to sell it? Seriously, I'm not asking to be a prick. I want to know what plan B is. There's been a couple of "I'm going to ask them to sell me their car" posts lately... and I want to know if people have backup plans for it the question falls on deaf ears.
