Importance of Considering Fuel Consumption
Fuel consumption is a key factor to consider when purchasing a car. Fuel-hungry vehicles may seem attractive due to their design, power, or technology, but they can generate high operating costs over the long term.
Furthermore, the environmental impact is considerable, as these cars emit more polluting gases, contributing to climate change.
