What is the meaning of 准新 in 由于二手车市场准新车越来越多...?
Yes, I think so. And it's just like someone who has just bought a new car and doesn't want keep it anymore, selling it on the secondhand market. Then the car he sold can be called “准新车”. “准” in Chinese always means nearly but not exactly. For instance, “准老婆” means your girlfriend and she is very likely to marry with you in the near future.
