Could you point me/us to even one review (other than wannabe YouTube car "reviewers") that claimed Stingers have "lots of" extraneous noise issues? I'll allow that some do, enough to hear about. But just judging by the relative lack of responses to these complaints made on this forum, this tells me that the great majority of Stingers do not rattle, creak, groan, squeak, crackle, pop, snap or otherwise annoy their passengers with noises that don't belong there. (Maybe it's time for a dedicated Stinger Forum "noises off" poll; sound off about how annoying your Stinger is to drive in because it won't shut up, etc.)
