instead of encouraging you to dump your car i will challenge you to keep it and fix all the issues.
you are going to trade school to be a mechanic correct? you are going to see cars like this constantly. to become frustrated and chunk the whole thing wont be an option when someone is paying you to fix the problems.

step back from the car and grab your pen and paper. write down everything thats wrong and separate them into sections were they seem related. start with 1 issue and fix each problem. if you get mad walk away. take a break.
once you conquer all the problems you will have a car that performs and you will be a leader on here and elsewere like rcompart, woody, miker, and brianbrave just to name a few.
your trade school teachers and classmates can be your best assets. you have acces to equipment and people with knowledge. make a project out of the car and enjoy the trade you are seeking. you have a lifetime of wrenching in front of you. look at msready's thread. 9000$ to fix his electrical problems and those guys didnt have a clue! he could have easily abandoned the car but stuck it out and now he has a rare srt-6 vert that makes him smile every time he gets in it!
