At the heart of any marketplace lies the fundamental economic principle of supply and demand. The price of cars often fluctuates based on these factors. When demand for a particular model increases—perhaps due to favorable reviews, celebrity endorsements, or rising trends—the price may rise due to buyers’ willingness to pay more. Conversely, during economic downturns, consumer confidence wanes, leading to decreased demand and subsequently lower prices. The COVID-19 pandemic, for instance, caused significant disruptions in both supply chains and consumer behavior, resulting in unprecedented changes in car pricing.

The advent of electronic fuel injection (EFI) systems in the late 20th century marked a significant turning point in automotive engineering. EFI systems replaced carburetors by using sensors and computer controls to optimize the air-fuel mixture in real-time. This technological shift offered numerous advantages improved fuel efficiency, enhanced performance, and lower emissions. Consequently, carburetor engines began to fall out of favor, and newer vehicles predominantly adopted fuel injection systems.
