Since the car is equipped with a 3.0T engine, the fuel consumption is relatively higher, but the specific fuel consumption will vary depending on driving habits and road conditions. According to online reviews, the comprehensive fuel consumption is approximately 12 - 15 liters per 100 kilometers. In terms of daily usage costs, although Mercedes-Benz is a luxury brand and maintenance costs may be slightly higher than ordinary brands, this car has been fully maintained at 4S stores, with good condition. The mall offers a 359 yuan in-depth inspection, 1940 yuan for preparation and maintenance, as well as a 30,000 yuan vehicle protection fund and 60-day full vehicle warranty, which reduces the usage cost to a certain extent. Moreover, the price of the vehicle is expected to remain relatively stable in the next three years, and from a long-term perspective, it has a certain cost-effectiveness.
