Fine Print, yadda, yadda:

Parts left here with no intended scheduled work after 90 days are considered abandoned. I know that may seem harsh, but it happens way too often, so here's the deal if you send something here, change your mind about having work done, and it stays here for 90 or more days after you have notified me of your desire to not get work done by Acme Speed Shop, and I have to store it, I will sell it for storage, which is 25.00 USD per month per box.  I am not free storage for your parts. If that happens any and all proceeds for the sale go to Acme Speed Shop, period. Now if you have something here scheduled for work, and you intended to have work performed, then we will work together, and I have no intentions to get your parts out of my shop.  If parts are here, and you are not having work done, then we can pack it for how we determine it should be properly packed to ensure safe shipping, this labor is no different than normal shop labor, 100.00 per hour, plus the cost of packing materials. Your second choice is to get a third party to come to pick up the parts and you two deal with packing and shipping.  On engine and cylinder head work because most of our work is performance or race, there is no implied warranty, and any warranty that we mutually agree on has to be performed here and it is your responsibility to get it back to us. Now if a part you or we bought in good faith fails, we cannot be responsible for any part failure unless the manufacturer offers a warranty, and because of the nature of performance and race use, most do not offer any warranty. At the end of the day, know we have built many of these engines, and have an excellent reputation for our work, and we try our very best to do all work at high standards. Our goal as always is to satisfy you.
