I have been trying to decide whether or not to wait and purchase a Dual Motor M3 and more likely than not forego the full federal rebate or to purchase an M3 as soon in Q1 2018 and take advantage of the rebate. This led me to think about what will happen to used M3 values in Q2 of 2019 when the rebate will more than likely be completely expired. Will the value of these used vehicles be tied more closely to the net price paid for the vehicle or the price of a new vehicle of similar configuration? My gut feeling is that if I choose to sell my M3, which I purchase with the full rebate in 2019, I will be able to offset most of the depreciation from the effective $7500 price increase that will occur as a result of the ending of the rebate. Just curious as to what others think.
