Question

She said to me ,"I will buy a used car because it is much cheaper."（改为含有宾语从句的复合句）it is much cheaper 在变为从句后，需不需变为一般过去时，还是属于客观事实，仍用一般现在时。

Answer 1

She said to me that she would buy a car because it was much cheaper. 楼主你好，你可以深入到具体情景中去理解，car的价格只是当时的价格，会发生变化，所以这里不可以理解为客观事实，应该用过去时：it was much cheaper.
