Some time ago I was standing chatting next to my vehicle in a parking lot. This was in college. About 50-60ft away was one of the lot entrances. Not too steep, though one of those that will catch a lower car if it doesn't come in carefully. Anyway, in comes screaming a Lamborghini. The very expensive sound the bottom of that car made still makes me wish I was recording. Could've turned it into my morning alarm.
I like to think me bursting out laughing still haunts the driver to this day.
