Yeah, it is pretty funny sometimes.
I got a look at the first post and realized I missed the part about naming/posting a picture of the cars. I was in a bit of a rush the first post, so I will post a few more comments I've heard.
1970 SS 454 Chevelle
"I can tell it's got a cam in it." (I usually want to reply, "It wouldn't run very well if it didn't now would it?")
"What is that whining sound?" (In reference to the Muncie M22)
"What kind of engine do you have in that thing?"
"Is it a real SS?" (I get that all the time)
"Is that car an LS6?"
"They didn't put 454's in those cars."
1971 Chevelle Malibu
"That is an ugly vehicle."
"Nice car, dude."
"Sounds good."
"What is that whining sound? (Same transmission as the '70 has)
I'm sure there have been other nuggest of wisdom since I started driving them.
