What is the difference between traditional automobile maintenance technology and modern maintenance technology?

Traditional automobile maintenance is mainly manual maintenance, while modern maintenance mainly uses new tools and equipment.

The old buddy was right. There are a lot of replacement parts, but a machine is more expensive to maintain than a new accessory, and of course it will be replaced with a new one. If you don't change careers, of course, you are more willing. The cost of working hours and materials is profitable, but the driver is not an idiot. New is better, of course, we change more.
