These ideas, like sparks, always lead to something bigger. One thing just leads to another and pretty soon you have a pretty cool-looking off-road machine. Michael Hendricks of Santa Margarita, California, had an imaginative idea and got to work on it. Let us explainits lightweight, its bombproof, and its a Toyota. Well, kind of. Its actually a tubular-bodied hybrid of mostly Toyota parts and Mikes suspension ideas. While on our mission to find fresh air, warm sunshine, and hard-core wheeling, we found Mike and what he calls a 2000 Rockota. The Toyota/rock-buggy was built for two reasons: (1) to go rockcrawling and (2) to try out his suspension ideas.
