I used to have my used car dealers license so I bought and sold a lot of cars. However one of the first ones I bought was a Suzuki Samurai that I bought out of a backyard for $200. Funny thing was it was about a block from my shop, it started right up after tossing a battery in it and I drove it to my shop. I cleaned it up right away and sold it to the guy that lived across from my shop for $1,200 the next day.
I would have loved to have kept it a bit longer because it would have been a fun little 4x4 and was cheap. I needed the money though, because I was just starting out but I always wished I could have kept that one to play with for awhile. In fact I wish I had it now with the current gas prices..
