As a young teenager - 13 or 14 years old - digging around in junkyards I learned a lesson that has stayed with me always. When you see something you want, you don't let it out of your sight until it's been paid for. I had plenty of friends who would see a hot item - a posi rear rend, a Hemi engine, an aluminum intake, etc. - and approach it with the idea that they had the luxury of thinking about it for a few days or getting around to picking it up tomorrow after school. More often than not, they were left with their dick in their hand and no part.
