Didn't they put the Toyota Celica engine in the Elise? I would not buy an Elise unless it at least had a Honda K20A2 engine in it. The REGENESIS Mazda Rotary engine would be really nice, too....
I'd go with the Crossfire. Speed is unimportant if women don't like the harsh ride. I'd rather have a woman in the passenger seat than my back glued to the driver's seat. The former is far more thrilling ;-)
