:Yes, the rubber mounts, especially the rear subframe bushings, have all 
gotten hard over time, especially on those cars which have lived in hot 
climates. My '69 came from SoCal and its rubber bits are particularly hard. 
I've replaced a number of them that were cracked and easy to get to, but a 
lot of them are still the originals.

That car rattles a lot when stopped in Drive, so I generally shift into N if I'm 
going to be stopped for long.

I never had an AT car when they were new, so I don't know if this is entirely 
due to age or if this is just the way they always were. We need to keep in 
mind that vibration isolation engineering in cars has come a LONG ways in 
50 years. I wouldn't be surprised if VW didn't think much about it back in 
1960, when these cars were designed, and when they came up with the the 
AT, I'd be surprised if anyone gave a second thought to the possibility that 
AT vibration was any different from MT.
