Have seen Corbins at the Detroit International Auto Show for the last two years. I was
not impressed with the build quality of those "cars" at all. The bodies were very flimsy, and for $15,000 I can get a loaded 2-3 year old Civic EX. Plus, three wheeled vehicles have inherent stability issues, which can lead to some very disturbing "surprises" while cornering. Also, with only one tiny tire driving the "car", I imagine that there would be very poor traction in the winter. Finally, a Geo Metro can take out a Corbin, just imagine what a full size vehicle would do to it in even a minor collision. If you want a good, well-build hybrid get a Honda Insight. The Insight is life size and actually has some luggage space. Insights have also been reported to get over 70 miles per gallon on the freeway when driven frugally.

EDIT: From Corbin: <<
In our rollover testing, we were pulling .88 Gs before the Sparrow would slide or come up (one-G would be sideways force equal to that of gravity). This number is very much in line with the average small/midsize car sold today. We've read magazine reports that place a recent model Ford Mustang at .86 Gs before it would slide.>>
Maybe so, but there is still an inherent difference in the physics of a 3-wheeler, there are no two ways around that. Also, when a 4-wheeled vehicle lifts one wheel (usually the inside front tire, and actually a common trait at high G loads) there is a wheel daigonal from it to prevent a rollover. In a 3-wheel design this is not available, and a 3-wheeler will prefer tipping to a lateral drift. Finally, G's pulled on a skidpad are a terrible way to measure lateral stability, a much more accurate test is a slalom course which subjects the vehicle to rapid directional changes. Rapidly altering the direction of travel ("swerving"

upsets a car much more than a run around a skidpad, and I doubt that the Sparrow is equal to anything short of Semis and delivery trucks in that regard. In short, though it may be able to handle a continuous G load that is applied slowly, I have serious doubts about its ability to resist rolling when rapid changes in direction are necessary. Again I say, look at the Honda Insight.
