The sample used in the research comprised 400 consumers using car care services in Amphoe Muang Chon Buri.

The results of the research showed that there was no difference in loyalty between customers with different gender and occupation.

The analyses on the relationship between marketing factors for the business and the customer loyalty demonstrated that every aspect of the marketing factors had a positive relationship with the loyalty. For the prediction power testing, it was found that there were only five variables that could be used to predict the loyalty. Those variables were location, product diversity, price, service, and shop design and display of goods. The analyses on levels of customer loyalty towards each aspect of the car care business showed that the overall confidence was at a very satisfied level, the centrality at a very satisfied level, and the accessibility at a very satisfied level.
