What are these x brands worth?

I'll do some research on those cars & see what i can find, that bird has a nice body, if it has limited rot, i'm saying a fairly solid car, its worth bucks in a good economy, its definitly worth more then your Swinger, what does this guy want for it, would he trade straight up, if he knows his GMs, i'm sure he won't, maybe for the Chevelle, but not the bird, the economy is really dropped off in the classic car market, who knows, it may never come back, it is a buyers market right now, but if these cars never get back in the game, you'll be stuck with them, then what, Its a barters market, trade-trade-trade, thats what people are doing, so if that bird is as solid as it looks in the pics, & isn't loaded with mud, & you can trade "straight" up for the Swinger, "jump on it", i'll garuantee the bird is worth double what the Swinger is, if not alittle more, just a few years ago, those 67-68 firebird conv. would bring 40K easy restored.

There are Firebird Forums out there, google them & snoop around, go in the 4-sale sections & see what there bringing/asking for a car like that.
