I realize that ordering a new Tesla means paying MSRP... but for CPO, is there any point in me trying to negotiate? If online tools like teslainventory.com are accurate, I can see the car I'm looking for has sat in inventory since February at my local showroom. They've dropped the price a bunch of times (and the mileage has gone up a couple of times, but minor - test drives I imagine). Can I play hardball and ask them to drop it further? How much further? Anyone have any luck? I'm kind of wanting to ask them to eat the tax (15%), but I'm guessing that won't fly. Its about equal to the amount they've already dropped it since February. Thoughts?
