I take almost everything off if its in good shape. All body panels, wheels, gas tank, exhaust system, most of the interior, trans. The engine i save for last and let people take what they need off it. It saves me time and hassle of getting it myself. I charge a little more if i have to take it out myself though. I also base all of my prices off the biggest junkyard we have. If they charge $40 for a fender, then ill charge $35. On a $500 car, i can get nearly $1000 out of it as long as its a popular model
