Thanks for the kind words Jeremy, and everyone else.
We (as in my wife, 3 kids, and myself) really need a newer vehicle with some room. Presently, when we go away anywhere, we cram in my wife's Dodge Grand Caravan, which has always been pretty reliable, but a mini-van simply isn't what her or I have ever wanted. If I sell the Mustang, I can also sell the mini-van and buy a pretty nice SUV, and most importantly, not have to get a loan. We have four vehicles total, the Mustang, the minivan, my Ford pickup truck, and my wife's "old" driver, an 86 Lincoln LSC. Ultimately what I'd like to do is sell the Mustang and minivan (for a newer vehicle), sell the Lincoln for a smaller econo-car, and keep my truck for my daily driver...
If I don't get any serious bites soon, I'll probably just forget about selling the Mustang, and just sell the Lincoln and van, and take the plunge for a brand new vehicle...
