Another encounter with a "youngster"

sounds just like the time a guy asked what I had under my hood.

Conversation:
guy: I just saw your car over in the parkin' lot. Looks nice.
Me: thanks I appreciate it.
guy: that has to have a huge engine in it I know it does.
Me: laughing...I just like to convince people I do, it's actually a slant six.
guy: Oh man that's one of those big hemi's right.
Me: (trying not to make him sound ignorant) um no sir, it's a 225 slant six.
