I dont know about Pontiac I go to Flint town....What ever you do dont go to the one in Waterford off of White lake rd next to campers paridise I dont remember the name but the are not freindly you get way less for material and their yard is a shit whole. ( I know its a scap yard but most of them actually take the time to clean them up and try to move harmful debris that can damage their customers vehicles. They dont.)
$.87 for aluminum wheels is a real good price. I just cashed some in a week ago and they were only $.74 a pound. Scrap cars were up to $135 a ton last week though. Thats down from the $200 a ton it was going for earlier in the summer but much more than the $80 a ton it was selling for last fall. I go to either Black River or Padnos.
If you want to scrap it as scrap iron, it doesn't matter what you do, I pitch whole engines with wirings, hoses, belts, etc.
If you want ALUMINUM pricing, you need to strip it to bare aluminum, get all the bolts, studs, etc out of it. So I assume that means you need to press out the cylunder liners, too.
The guy in the back always is telling me how much money I lose when I just scrap transmissions, etc, instead of taking them down to bare aluminum. Its not worth my time to get $20-$50 in aluminum, I just want the shit gone..
