I'm 6'1" and I like my Crossfire, and I like horsepower. If more horsepower came without much of a price increase, I would say "yes" it would help the sells of the car. But as far as the 215 horses that came in the Crossfire, at just under 3,000 lbs. weight, this thing goes. It's looks and Appeal, that sells it. If horsepower sold this car, I would perfer to have the HEMI option, but then what would the price be?
