Built with a M47 Patton tank engine, a Continental AV 1790 5B, this street-legal vehicle was built by a glass artist named Randy Grubb in Grants Pass, Oregon. It housed an engine that weighed 9,500 pounds and operated at 810bhp, brake horsepower or the power that actually reaches the wheels. Made with a strikingly ornate aluminum body worthy of the title, "crystal tan," Jay Leno bought it for $125,000.
