KBB is a useful starting point, but it's not the end-all answer. I just sold an Acura TL. KBB indicated $7k for the mileage, but I was seeing similar cars going for $10k on forums. KBB didn't price in the timing belt replace, new tires, the rarity of the manual, and the Type-S package very well. Sold it for well above KBB to someone who had looked for that car, with the MT, for a long time. He could wrench on it, so I felt good giving him a deal, and he made it easy for me to sell it to him (wasn't a PITA). Given that the e39 M5 is similar in many regards (rare sub-model of a somewhat common, but older car, enthusiast drive, maintenance intensive)... I would only use KBB as a starting point. And it's also probably the floor of your pricing. Do a search on forums, online sales sites, and then put up what you think is a good price. Potential bidders will let you know what they think it's worth.
If I look up 2000 M5 with 108k, then I overpayed for my m5 by a lot. What it doesn't know is that I was able to talk with 3 of the 4 owners, one of the owners maintained it for 10 years (owns shop), and he could tell me exactly what had been done, when and what needed to done. The other guys were helpful in filling in blanks. And it's a Dinan S2.
