My colleagues laughed at my used car because it was too cheap.

How much is a used car? I hope you don't care too much about other people's eyes! There are many people around me who buy used cars. I don't think there's anything wrong with it. Some people buy 200,000 to 300,000 used cars, while others buy/kloc-0,000 new cars. Each has its own needs and its own vision. All with your hard-earned money. You can be more confident next time. Don't think too much. Colleagues watching lively jokes also improvise. As long as they are satisfied, that's enough.
