Example, that is a comparison between Honda Jazz vs Volkswagen Up, the price is almost the same ,value start from $14,990, two also hybrid car ,if one of the car raise up the price the another car will also raise up the price, that is because it is the same type car and if one of the car raise up the price and the another car price stay constant , it will lose in the market .
