mercedes which has many poorly rated and certainly unreliable cars which are more expensive than many other car companies, has advertisements which dont promote rational decision making'
a rational reason for buying an SUV might be if you live in a back road with no snow plows. if you dont need the space and live in the city, you might not be making a rational decision when buying an SUV.
point is advertisements dont promote rational decision making. i wil now search mercedez suv ad and i will post the commercial here and you decide whether its promoting rational or irrational decision making.
