Just to chime in, this guy may not get the 18K he's looking for but...lets face it, the car is in pristine condition. A few years down the road it may get every bit of that asking price. Many of the bullitt owners are "older" (no offense guys) and keep their bullitts stowed away as a throwback to their youth and have a great deal of sentimental value to them growing up with McQueen on the big screen and all.
Your frustration with the guy being anal is understandable, but sometimes you need to look at things from another point of view
Being a bullitt owner myself, we are like the forgotten brother of the GT and Cobra. The bullitts just didn't get a unique enough of package to be all that different from the rest IMO. It's kind of a pain in the ass explaining to people what makes our cars different from the GTs. To many the difference is negligable. I don't know if it justifies an 18K pricetag, but to someone it may.
