I am one of those traders too.. Almost 2 years ago me and my wife had our first child. The vehicles we had at the time were her 2002 cavalier z24, and my 1994 Ford F-150. Well we decided that we needed a bigger "family" car. So I started looking around and some friends of my parents had a car for sale. A 1994 suburban. Plenty big enough and being 4x4 good and safe in the harsh winter months. And they only wanted 2k for it.(at the time it blue booked for just over 4k since it only had 60k miles.) So I went and looked at it, test drove it and I bought it. We kept it for a while but long story short we drive too much for work and gas prices were killing us. So I started looking to trade it off. I had always wanted a GTP and found some one with a gtp wanting a suburban. We each met up and test drove each others car and traded.... Win win.
