参考答案

正确答案：C
解析：W: I'm going over to see a car someone has for sale. With all your experience as a mechanic, I'd appreciate your opinion.
M: That was twenty years ago. Cars have changed so much. I'm not sure how much help I might be, but sure I'll come along for the ride.
Q: What does the man imply?
分析选项可知，对话话题可能与车有关，其中两个选项都以He开头，故男士的话为听音重点。综合男士话中的客观事实(Cars have changed so much)和其主观认识(I'm not sure how much help I might be)可知，他对现在的新款车了解不多(doesn't know a lot about new cars)，故选[C]。
