I drove an altered for a local guy for 2 years while I was building my car. What I liked about it was the visibility. You can see the front wheels. What I didn't like was getting a face shield covered with coolant, gasoline or oil. You are out in the weather, when it's cold outside it's a lot colder at 140 mph. Also when it's hot and sunny outside it's a lot hotter sitting in the lanes. I also didn't really care for the wind buffeting my helmet at speed.

I'll stick with my door car.
