"It runs completely on bio-fuels."
"What's its top speed?"
"It can cruise at about 25kph, with a top speed of 50kph."
"It seems kind of expensive..."
"I think you'll find the price is actually very competitive, plus we accept eCash and CarbCreds."
"What colours are available?"
"Back when they occurred naturally, there were only a few basic colours, but we have pretty much any colour you like."
The customer was silent, not quite sold.
"We also have several option packages, including a horn or wings."
"Wings?" the customer asked, intrigued. "Can it--"
"Fly? Not yet, but we're working on it."
