I would aways use Consumer Reports as a gauge of "reliability" when purchasing a car but basically ignored it when I purchased my MS a few months back because:
1. Some car manufacturers had a multi year (even multi decade) pattern of producing unreliable vehicles...those i stayed away from. Tesla hasn't been around that long and everything points to more reliable vehicles going forward.
2. Elon Musk stated about 20 improvements are made to the MS weekly, and many fixes occur over the air without needing to bring the car into the shop.
3. Tesla has a proven track record of taking of their customers. There were many stories of early Tesla adopters being taken care of even when an issue wasn't under warranty etc.
