Was it a black A8?
I have seen mostly American cars. The most impressive was an old Monte Carlo SS with it's floor pan bottomed out near Ballona Creek. Correct that.... The old lady that was slow motion "rim riding" a newer Buick sedan down the hill. She ripped off her side view mirrors between the concrete posts on the Manhattan Beach Pier. The man who power washes the pier barley stopped her from driving off the end of the pier. She was the picture of the "little old lady from Pasadena" or one of the "Golden Girls".
