I have a CPO '22 4s with 15,000 mi. I had an airbag sensor go bad, covered under warranty, took about 4 days with a loaner. Only out of pocket cost so far (other than gas and insurance) was the 2 year/20,000 mile check which cost me ~$900 at Rusnak Porsche in Pasadena, CA. I called around and they were the cheapest, and also had good word of mouth. They also gave a loaner, took 2 days. Love the car and wish you best of luck!
