I just do the rebuild stuff for me and for resale if I come across a machine at the right price. I have a two car garage in which my side was a machine/work shop for the last 17 years. I had to move/sell/give away a lot of stuff to be able to get a car in on my side. Wife won't give up her side during winter and the lot layout won't allow me to expand. Getting close to retirement and hoping to come up with a few widgets to make and sell to keep me busy. I've been repairing BMW E39 M5 oil pans for several years because parts for those cars are crazy expensive.
