Depends on the part and the demand. I have sold used parts for years. I start with retail pricing, and then look at the part I'm selling. I sell most parts for 50%. If a tail light or arm rest lists for say $100, I sell it for $50. There is not much difference between new and used on items like these. In fact they are better than new, because every time you walk by your car, you don't have to look at one sparkling new tail light and one weathered one. If the buyer wants to save $30, has has the right to search the U pull it wrecking yards if he has nothing better to do. Electrical items like starters and blower motors go for about 10% to 20%, because there is a big risk factor in how long the unit will last. Some parts of the car may be worth several hundred dollars new, but you recycle them with the scrap, because no one ever needs them like valve covers, etc. Some electronic components almost never fail like seat memory modules, so they should go for several hundred dollars to someone who unfortanately had one fail.

Hope this helps,
Peter
