I guess I haven't lived with my FR-S long enough- I don't know what the cricket sound is and I guess I don't really care(?)
Maybe at the next meet up one of you that knows what it is can listen yo mine and tell me if I need work done
To me it is a new car and everything sounds good

My new Yaris runs so silently quiter than my old 05 Corolla, the FR-S does have more engine noise at idle but, meh?
