I am a single mother and physician and need a reliable car. My 2 year old Model X was towed to one dealer and the been towed and the loaner was towed for a flat tire in the middle of NYC the very next day. I have not heard from service in 5 days despite multiple calls. Any advice, thoughts anyone can share? I think the idea of a luxury car service that works one way (they call you, you can't call them) is terrible. This may be a one-off horrible experience, but if I treated a single patient this way I would have no practice. Any advice?
