I planned to take delivery in Devon, PA. In NJ there is no sales tax on EV but in PA there is. Based on my research, including speaking to someone who has delivered cars in Devon to NJ residents, there is no sales tax applied to the purchase price if you register the car in NJ. She told me if I did not change my delivery location to Paramus or Springfield I would be charged tax. Again, based on my research, that is not true. That said, I complied and agreed to change the location to Springfield despite my preference for Devon or Cherry Hill. If taking delivery in Springfield means a smoother transaction on the tax and registration side, fine, I will go there. I've heard good things about Devon and it is only a few minutes further from my home than Springfield and a much better drive so I wanted to go there. Alternatively, I have heard a few not so great things about Springfield.
While she is wrong I give her credit for trying to do something that she thinks will be better for the customer.
