I live in San Francisco, I rent a small apartment in a fairly nice neighborhood. Without fail, every night parked on the street are 2 Audi S5s[1], a Tesla Model S[2], an E63 AMG Wagon[3], and a smattering of Porsches (new Boxters to oldish 911's).
Surprisingly it usually works out fine to park a totally empty $100k car on the street in SF, but if you leave $0.25 on the seat of a $500 toyota, some crackhead homeless fucker will break your window ($100-300 to fix it) to steal it.
