I am a very busy Real Estate Salesperson in the GTA. I have been considering the Model S. Currently driving a beast of a Mercedes AMG but it's coming time for a change. My concern is that there seem to be many issues owners have been having. Sometimes the service sounds like its great, other times sounds poor. How has your service experiences been? How about reliability? Do you think this car would be good for my occupation. I put 30k per year.
