The work was undertaken to measure and assess the quality of motor car maintenance and repair services with using the SERVQUAL method. In the investigation, the survey method was used. The inquiry form consisted of two parts. In the first one, identification questions were asked to define the customer’s profile, characterizing the car user. The other one included substantive questions of the SERVQUAL inquiry form. Pursuant to the basic lines of the SERVQUAL concept, the discrepancy (gap) between the perceived and expected quality of a motor car maintenance and/or repair service obtained was examined. The diversity in the quality dimensions was analysed in relation to variables in the customer’s profile. A data analysis based on car users’ profiles has provided grounds for a statement that the widest gap was indicated by the respondents who had been car users for over 41 years. This result reflects the requirements regarding the quality dimension labelled as tangibles. The only positive value of the quality gap was recorded for the dimension referred to as responsiveness and for the same group of car users. This means that the expectations of the most experienced car users were lower than the perceived value of this dimension. The variable that in most cases diversified the assessment results was found to be the time of being a car user. An analysis of the literature data available has revealed that the SERVQUAL model has not been used to date for measurements of the quality of motor car maintenance and repair services; thus, the attempt to fill this gap may be considered an innovative element of this study.
