Royal Oaks Parts Department has received mixed reviews from customers. Some appreciate the service, noting that the staff, particularly Andy and Barbara McCoy, are helpful and keep customers informed during repairs. However, there have been concerns about the time taken for vehicle diagnostics and repairs, with one customer mentioning a prolonged wait for their truck to be fixed. Additionally, some customers expressed unease over a staff member seen joyriding vehicles, which they feel reflects poorly on the business. Overall, Royal Oaks is recognized for its efforts to improve service and maintain a good relationship with customers, especially those with Chevy vehicles.
