Sweet sounding slant

I must admit I am the complete opposite. I am most impressed by a neighbor's 50's Pontiac straight-8 that you can barely tell the engine is idling. We were once given a new V-8 Mustang rental since all they had besides a trunkless econo-box (reserved a compact). We returned it and swapped it for a Jap sedan after a day. Our daughter was cramped in the back seat and couldn't see out the window, but worst was even slight use of the accelerator gave a roar and seemed other drivers glanced at me like I was a dum-a$$ kid. Perhaps just a fake engine sound from a speaker in the cabin like some new sports cars use, but seemed stupid to me to get so much noise when driving moderately.
