In the process of buying a car, I mainly use three softwares: car home, Zhichehuang and Easy Car. Car home provides comprehensive vehicle information and user evaluation. Knowing Car Emperor mainly provides video content, providing all kinds of vehicle evaluation and disassembly videos. Easy Car is a car buying platform, providing car buying calculator, financial planning and other functions. These softwares are very useful, but the final car purchase decision needs to be combined with your own needs and budget.
