Bahnstormer I ran NADA, the most used on the west coast and got 22-26, I ran KBB and got 21. Did you notice the mileage is 7900, not 79000?
I agree with you Tom, I'd check those entries on Carfax. They had about a dozen on my 318is, yet the only two owners were my brother and I. I believe they listed it sold in Germany, then he ships it home, registers it, etc, etc. Best to check though and be save.
