为什么用have been?
为啥不说it must be expensive?
答：It must be expensive.是对现在情况的肯定推测：这车一定很贵.
It must have been expensive.是对过去情况的肯定推测：这车当时一定很贵.
什么时候说什么话.所以说话者为什么要这么说不那么说,要看上下文.要回答你这个问题,需要你提供更多的上下文.在没有更多的上下文的情况下,要回答：
Take a look at that car.It must have been expensive.这句话的语境和意思,只能发挥我们的想象：比如我们去博物馆参观某名人曾坐过的车（现在都不生产了）,指着它说：请看那辆车.当时一定是很昂贵的.（现在?无价!）
