What is the equation that defines a perfect car? Automakers are well aware of the fact that people want to buy the “best” car available. Hence you see advertising slogans like “Pursuit of Perfection” (from Lexus). According surveys, Lexus is probably the closest car to being perfect in terms of reliability. Lexus is also known for being one of the quietest cars. (Remember the old commercial with a stack of champaign glasses placed on the hood while the engine was running?)
