In order to assess the value of a model, it is advisable to compare supply and demand. The available (used) supply of the E 64 (without reimports) is determined by the registration numbers (here from the end of 2014). Demand is based on the comparison between the available quantity in relation to the total availability (x % of the total quantity is currently available). E 64 Supply of 945 = 6.56 % 630 : 77 of 1178 = 6.54 % M 6 before facelift : 24 of 271 = 8.86 % M 6 LCI : 12 of 271 = 4.43 % 650 before facelift : 46 of 315 = 14.06 % 650 LCI : 16 of 630 = 2.54 % 630 before facelift : 59 of 781 = 7.55 % 630 LCI : 18 of 397 = 4.53 % The most sought-after model in mid-2015 was therefore the 650 i (LCI) with 2.54 %, the least requested model of 650 i (before facelift) with 14.06 %.E 64 supply / demand in mid-2017 : M 6 : 33 of 271 = 12.18 % 645 : 62 of 918 = 6, 75 % 650 : 50 of 945 = 5.29% 630 : 68 of 1178 = 5.77% M 6 before facelift : 25 of 271 = 9.23% M 6 LCI : 8 of 271 = 2.95% 650 before facelift : 47 of 315 = 14.92% 650 LCI : 23 of 630 = 3.65% 630 before facelift : 53 of 781 = 6.79 % 630 LCI : 15 of 397 = 3.78% The most demanded model in mid-2017 is therefore the M 6 (LCI) with 2.95 %, the least requested model of the 650 (before facelift) with 14.92%. n Models : M 6 (LCI) 630 (LCI) 630 (before facelift) 645 Sinking demand (or increased supply) is available for the following models : M 6 (before facelift) 650 (LCI) 650 (before facelift) The (still) increasing demand of the 645 (or the lost supply) is due to the low entry price (cheapest eight-cylinder). This can be seen from the fact that the 650 before facelift models perform exorbitantly worse compared to the 650 LCI. The most stable value (short supply) are (as in 2015 forecasts). The M 6 (LCI) and 630 (LCI).
