Speaking for myself *only*, I do indeed want to hear the engine - but I don't want to hear the exhaust that much if that makes any sense. I used to be able to hear the valve train in my old 240D Mercedes, and I could tell when it was "floating". My current 300SD has the same engine family, but I can't hear squat because of all the sound proofing, but there *is* an annoying resonator underneath the driver's seat which I really don't like the sound of. The old '63 GMC V6 we had as a boy didn't make all that much exhaust noise either, but you could hear the engine itself (and the lovely SM-420 transmission which sang to the driver!). When I was 17, my dad bought a '78 Chevy with a 454 - and its exhaust was reasonably quiet so you could hear the engine itself. They all talk to a driver who knows how to listen.
This Jeep is the very first inline 6 I've ever owned. The inline sixes my parents owned were gone before I was born, so I have no experience with one. I find it to live up to its reputation, very smooth! I can hear it up there under the hood just fine. The cars/trucks I grew up with didn't have tachs, so I'm used to shifting by ear, although I've found the tach can make me more precise.
