The Hummer H1 has been on the market for 14 years, and in that time sold nearly 12,000 units, but now it's time to say goodbye. The 2006 model year will be its last. In 1992, the Hummer came to be when HUMVEE production decreased, making room in the factory for a consumer version. Now that the H1 Alpha is gone, the assembly lines will be converted to making HUMVEEs again. For one of the last tests of the H1, check out this year's Ultimate 4x4 Challenge.
