I finally got my wife on board after the last test drive this past Saturday. Now it's trying to sell my 2017 A4 before I order the M3. Anyone have experience with trading in a vehicle on your M3 purchase? I'm guessing since they don't sell anything but Tesla and they don't seem to have wiggle room on pricing, it's probably a fool's errand to trade in. However I would get some of my sales tax back on a trade-in. Selling it outright could take time. I've posted the vehicle to CarGurus. Any other places? Just trying to maximize my values and appreciate your thoughts here.
