Be glad you didn't buy it. First, he wants too damned much. Especially for the mileage. Second, a car having gone through a severe front-impact will never, ever drive the same again. You can replace everything, straighten the frame, even pray on it, but the car just won't ever be 100% again. You can get them close, but you don't pay $20,000 for 'close'.
i highly agree. you can get a ms6 for 15 with 30k miles on it.
