High pitched intermittent humming at 60+mph
I got a new-to-me 2000 Jaguar XJ8 V8 4.0 a few weeks ago. 41k miles, kept up to date on all maintenance per written records. It came from a woman in Florida who obviously didn't drive it often.
While driving on the highway today, I heard a loud, intermittent humming noise when I hit about 60mph. I slowed down a little and the noise stopped, so I pushed it back up to 60mph and the noise continued, still intermittently. It will hum for 1 second, stop, come back and hum for 5ish seconds, stop, come back for 2-3 seconds, and so on. It's never steady for longer than about 8 seconds. The further I went, the less it got until it completely disappeared at 60mph. I then picked up to 65mph and again, the same noise. If I slowed down to 60mph, it was gone. Again, I got back up to 65mph until the noise stopped, accelerated to 70mph and again the noise returned. When I slowed back down to 65mph, the noise was gone.
Helpppppp!

Congrats first of all on finding a 17 y/o Jaguar with 41k miles.
As for your humming noise, does the noise sound like its from the front or rear? Is this on a fairly flat road or does the noise happen when you hit a bump in the road? Anything in the service records to indicate any repairs made before you bought the vehicle?

The noise sounds like it's coming from the front end. It's only happened on the highway so far and that's a pretty flat, smooth surface around here considering the highway has recently been repaved. The car was in a t-bone collision many years ago without any damage to the front end.

It sounds like it's coming from the front right side to me. My boyfriend said the same thing, but he describes the noise as "someone playing a harmonica". I think it sounds like a very loud humming, almost like you're going over rumble strips but without the vibration.
