<prompt> Human: There are about 30 cars in various states of disrepair. There are also three 20x40ft tarp sheds with various parts. The house is full of repair manuals, original owners manuals, pins, scale replicas, and other various stuff. Mom wants to sell everything and move closer to me and her first grandbaby.We have lots of family and friends that are knowledgable about what everything is, but weve never had to liquidate an entire collection. Where do we start?  <response>: My wife and I dealt with the same situation a few years back when her parents died. Her stepdad was also a huge AMC car collector and had a similarly large collection of show cars, junkers, and spare parts. He was part of a regional AMC car club and they were a huge help liquidating all of it. They helped us organize an auction and advertise it to club members and other clubs across the country. We were able to get rid of nearly all of it quite quickly. The rest went to a junkyard for scrap. I would suggest doing something similar. If your stepdad was part of a club, contact that club. Otherwise just contact the nearest club. Even if he wasnt a formal member, they probably knew him, its a close-knit hobby.I will warn you though, youre not going to get nearly as much money for the stuff as you think you will.
