How did I do

I'm 64 and have no desire to put sound deadening in any of my cars and I have owned a quiet car (2004 BMW 330ci convertible with sport suspension). These cars are not supposed to be quiet, in my opinion. Yes, you did well on that car. The closest we came to something like that was a '71 six barrel GTX running/driving for $600 (but I was younger than you are now). It was missing the six barrel stuff so I passed...

Yes, but have you ever driven a 440 sixpack automatic B body with a sound deadening package? The car should be quiet, the engine should not.
I didn't pass on a clean used 70 Super Bee 440 sixpack automatic in 1979 for $1000. Ten years later it got the premium sound treatment. That sound treatment made the car irresistible as a daily driver.
And yes, I did like my 2004 BMW 330ci convertible and 96 Z3.
