where do they put the tank? http://www.arnoldclark.com/used-cars/daihatsu/copen/2dr/2004-(04)/ref/arnca-u-16340/ either that or they have ticked the box by mistake.
Looks like there's something behind the bumper. Where the left tail pipe should be? Maybe a flat tank attached to the underside of the boot tray.
just noticed that - seems to only have one exhaust pipe as a result. wonder what the pence per mile is with such a conversion?
maybe worth doing on a thirsty car but probably waste of money on a Copen. I looked at it when I had a Forester (28mpg!) and they wanted £2000 for conversion.
