I'll leave these private party examples here for reference:




Note that a 200k 2008 135i in excellent condition is worth 43% of the same car with only 25,000 miles and a 100,000 mile example is about 2/3 the value of the 25k mile car. It's about a 10% drop in value for every 25,000 miles until 100,000 miles and then decreases to about 7% per 25,000 miles. That's because you can only go so low.
