Sam says he does 30-50% profit per car. Has 100+ vehicles sitting in his yard waiting to be parted out.
Another commenter in the thread does 300+ cars a year 
But you don’t need a car yard to start.
One member skips buying cars entirely. He cherry-picks at junkyards instead – grabs 10 of the same part, creates one eBay listing, then ships from that batch as orders come in.
And from another commenter…
Sold a tail light enclosure the other day for a chevy.. paid $5 at goodwill, sold for $80. i’ll take it. wish I knew more about cars..
$5 in, $80 out. No mechanical skills needed 
Most people walking past them at thrift stores and junkyards have no idea what they’re worth.
A junkyard trip, a basic toolkit, and an eBay account – that’s your startup cost
