So, you see the lack and then the offer of LEDs as a reason to change your car. Ok. Don't expect me to agree, though!
My reasons to change a car would be if it was involved in a chassis effecting crash, if I considered it unreliable (that's serious issues that come completely unexpected. Issues that result in the owner being afraid to start a two weeks trip with the said car) after a period of ownership or if I can't afford to keep it.
At least for me, the car is above all a tool and an expensive investment (given that I prefer to pay in cash for the car and sleep nice at nights, as opposed to the stress of monthly installments - I am a freelancer, so I don't have a steady monthly salary), so it has to pay off and work as its expected.
I can understand people that are motivated to change cars based on their fascination of bluetooth connection or a bigger screen, but I don't agree.
