Is it better to maintain the car outside or at a 4S shop?

[DeOlivia]

Generally speaking, 4S shops are not necessarily better than outside shops. If you want to save money, outside shops are more cost-effective, but you must choose a shop that can guarantee the quality of maintenance. Below are some precautions for car maintenance: Labor hours: When repairing a car, the hourly fee is usually included. If calculated separately, it would be duplicate billing. When replacing brake calipers, the brake pads need to be removed, and the labor cost for replacement should be included in the repair cost. If the bill includes separate labor fees for caliper repair and other items, you can argue with them. Mileage: When the car has a serious problem and needs to stay at the repair shop for a while, remember to note the mileage. This is to prevent unscrupulous mechanics from taking the car out for joyrides. For general repairs, even if test driving is included, the distance should not exceed 20 kilometers.
