a "Engine size" taken from actual advertisements.

b Data collection was attempted for all different vehicles (n = 149) and when available it was then extrapolated to the advertisements shown in the magazines.

c "Fuel efficiency" for the advertised vehicles was obtained from an official New Zealand website [9].

d "Greenhouse" and "Air Pollution" ratings are on a scale from 0.5 (worst, most polluting) to 10 (best) based on their CO2 emissions and other air pollutant emissions. These were obtained from an official Australian website [10].
