Good bye fox:( Hello 97 cobra:)

heres the story..i traded my fox that was running fine. and traded for his cobra. The kid said hes owned 6 foxes in the past so i assumed he knew what to look for. So i take his car on a drive with him and im nice and gentle with it just going threw all the gears. Then we go for a drive in the fox and with the engine stone cold he starts burning rubber out into the street and started driving it like he stole it. So we get back and we trade and he gives me 600 bucks on top to switch wheels. a day later i get a txt saying he blew the motor. i said are you serious and he said yeah i blew a head gasket. He seemed fine with it. So today i got a txt saying wtf dude theres colant in the oil wtf are you gunna do about this. I said umm you blew a head gasket wich results in coolant getting mixed with oil. and then he says "dude ive had the car for 2 days thats phucked" ..then i said "dude you blew the motor..you drive hard with the engine still cold, a 25 year old engine cant take that kind of abuse" then he has the balls to say "If your in the auto field i suggest you get a new job because the car is phucked" then i proceeded to say "who the phuck do you think you are? YOU blew the motor i never had a problem so its your problem" then he rambles about how i messed up the wiring behind the dash when ive never touched it. Wich i told him then he said "ok" and thats it so far..
