It sounds like something is wrong with the car’s engine.
, we’d better take it to the garage immediately.
A. Otherwise
B. If not
C. But for that
D. If so
解析：这道题考查状语从句的省略。句意“听上去汽车的发动机好像坏了，我们最好立刻去修理厂。”通过简单判断可知，这两个句子之间是顺承的关系，所以应该是“如果真的这样的话(发动机坏了)”。 Otherwise否则，要不然；If not如果不是这样的话；But for that要不是那样。以上三项均不符合句意和语境。If so “如果这样的话”，符合句意和语境。If so相当于If something is wrong with the car’s engine.所以正确答案为D。
