I hear ya on the parts, but ever watched eBay auctions for ST's?? I have for like a year now, and an ST that has grille and taillight guards ALWAYS goes for more on eBay. I know it doesnt help in a local market, but eBay it does. And if they have the tonneau cover and bed extender, even more. When a person buys a car on eBay all they are going by is the appearance, so a better appearing vehicle naturally sells for more on eBay every time (done a decent bit of eBay car selling).
BTW - you guys are the experts - think my buy it now price is a fair asking price? I had a hard time figuring out what to ask because you don't see many higher mileage ST's with low mileage motors in them.
