Man sorry to hear, decisions like these are tough. I understand about spending time with the one thing/person/belief that is most important to you , but thats it - there is no "one" thing, only many things that have different priorities. And you car is not just a hunk of metal, its something that you spent many hours/days/months on - something you take pride in and respect. I don't know your current situation & how everything came to be but at least try to
compromise, sit down and wieght everything out - it wouldn't matter if this was about a car, boat , plane h*ll even a dog - just talk mang smile and if you really have to sell one of the things you love to keep one of the things you love then you must - just my 1/2 cent, I just had the same problem or similar - my girlfriend now drives a faster car than me :p
