What has the experience been with trading in your '15 cat for a '16? I have the opportunity to order a '16 ( i found the '15 out of state) and to my specs. i have a '15 A8 in pitch black with about 5500 miles on it. Have you had better success selling it privately vs trade in? Indiana allows you to pay the tax on the trade in difference rather than the full value. Have a loan so would need to get that paid off and then save the extra cash towards down payment. I would consider buying a used car but wary of how previous owner may have treated them. I would be ordering a M6 this time around, LOVE the A8 but find myself wanting to row through the gears since I don't ever track it or any of that stuff. Thoughts?
