Should I buy a Porsche if I had to park on the street every night?

[Ted]

I live in San Francisco, so expensive cars are very common here, bmws, mercedes, audis, but still you don't see a lot of porsches around parked on the streets.
I'm planning to buy a Porsche Cayman or Carrera soon but the only way i can park is on the street parking. Do you think it'd be safe or do you think it'll be too much attention on my car??
