Hey bud not to be rude or anything but your in the wrong section
post them at the diesel disscussion section ... according to your discription that car is only worth $750-$800 and resale value is $2500 to $3500 is probally the most you can make off not much ppl like diesel because of the price of diesel fuel... if you do the math you going to make a little pocket money repairs including the price of the car is going to be 2.5K for repairs and parts... anyways good luck...
