You been drinking?? I tend to get alittle too open (on here too) when I've been drinking.
That is pretty heavy stuff but it sounds to me like it was a heat of the moment statement. I think he will probably call you and apologize, if he doesn't maybe you should go by there after a couple days(cool down time). I don't think an arguement is worth losing someone close to you, it happens alot, but life is too short to let some bs ruin the rest of the relationship. If this were to happen to me and my dad I would probably not take another car to his shop again, even if he said to. You argue when working on the car, so I wouldn't work on a car with him. I would avoid those things that cause the conflicts. You can find somewhere else to work on your car, believe me there are alot of guys that want someone to help with their car and want to help with yours.
Your dad was mad and so were you, he is probably just as upset as you are.. some people just don't show it that much.
Its really hard to look into someone else's relationship and give good advise, I wish you luck..
