Most important: Find a dealership that has a good service department, whether you bought the car there or not. Go in and talk to them. Some of them are terrible. Some are great. Ask any random questions just to see how they respond. See if they always have some bs answer or if they genuinely try to get you an answer or admit if they don’t know. Why? Because those people are the ones that have the leeway to help you or not care if something unusual happens and you get ripped off. Read bad car reviews and it always has to do with the service department. They have options. Once you’ve experienced a bad dept versus a good one, you realize it makes all the difference. (Also remember that service departments in more expensive neighborhoods depend on their excellent customer service and their prices aren’t necessarily higher — no one likes getting ripped off.) My 2 favorite service depts have been smaller ones (2-3 service reps) vs the huge operations.
