The RPM are 840 on both “N” and “D”, however when I throw it on the “N”, the sound goes away.I tried, having it on “D” and holding the brakes, to raise RPM to about 1100, and that is when the noise is most evident.The best described it is a very low intensity roar and slight vibration.

Craigslist Ad C70 Convertible Manual Trans

I post CL ads I find quite regularly in the MVS Forums’ Classifieds. I don’t have any involvement with any of them — I’m not the seller and don’t know the seller or the car. I always put a disclaimer in my posts like: I don’t know the seller, don’t know the car, don’t know anything beyond what the ad says, and don’t have any interest in this sale.
