The number of respondents who participated in the study were 82 people. The consumers were those who had bought the car. The instrument developed in the study was used to measure responses given by the consumers after buying a car. The instrument was reported by using Lakert 5 scale. The results of the study showed the reliability of Alpha Cronbach which was .78. Calculation of differential item functioning (DIF) score reached above .05. The result of the test item dimensionality (DIM) raw score variance was 36%; this affirmed that the items contain no other dimensions. Overall, this instrument is considered reliable to be used in measuring the factors affecting the decision to buy a car.
