I go to garage, yard, and estate sales. It's not only the low low prices but I think that older stuff is better. I believe that new stuff is designed for a short life expectancy. Old stuff has already proven it's ability to withstand use and abuse. Plus ... most of the time I prefer the look of aged stuff.
I drive a 1989 Dodge truck. It was leaking antifreeze when I bought it. I fixed it. Other than this it was in really good condition. My plan is to put 100,000 miles on this truck for under 10 cents per mile. When I sell it I'll probably get more for it than I paid.
