It seems this site is more for lookers than guidance, but I'm thinking of getting an M3. And like any car, it has scary stories. The screen stops working for 15min. The car won't open or start. Parts are expensive, repairs are slow and slower. The assembly quality is mixed... This looks like a great car - but I'm not sure I wholly trust Tesla. They can fly me around the moon, but for a car I rely on? I'm hesitant. We've bought nothing but Japanese cars since 1998. No more questionable Saabs, Volvos, VW's or MB's for us. We've loved owning these cars that NEVER see the service bay, except for things like tires and brakes. My 20yo Nissan van never needed service. Or my 12yo Lexus. Our 4yo Leaf is ready to take my wife to work - every morning, without fail. So in general, how nice has your Tesla been to you? Are you happy or sorry?
