There was another thread that had a kinda similar topic, so I'll interject what I said there and add a little more to it. The topic of the original thread was somewhere along the lines of
"when/where/why did G Body's suddenly become popular/worth anything?"
To which I replied:
"Well seeing the prices for even a ratty 1st gen F body, or A body, the G body and 3rd gen F body seem like the next logical steps for many people. Their popularity are (and have been) showing in the increased aftermarket support alone.
In 20 years people will be saying the same thing about G body's, and then the next popular platform will come around."
My perception on the G Body changed since I've owned it and really started to learn about them. I used to think that they were a hot ticket item, that they would be the next legendary A body or the like. Now I think a little differently.
I've always said G Body's are like legos. They are still pretty cheap, you can take parts from everywhere, pretty much do anything you want with them, a lot of times without major fab work. Which is great. G Body's are a great platform to learn with, they can be made to drive decently, and are an ok platform for drag racing. Autocross and road course racing stuff is a little trickier with these cars, but still plenty doable. You can thank the aftermarket for that.
I think there are a lot of people who still want that '70 Chevelle, or '69 Camaro etc. But because of the prices that is a pipe dream for many. For me, the G Body was just the perfect first car to learn on and start drag racing with. Before I stumbled across the G Body for the first time (shortly before I got it) I didn't even know what it was. I was looking at 3rd Gen F Body’s for the same reasons. They were cheap, easy to modify, and still plentiful. I didn’t think to myself
“oh I’m gonna get one of those 442’s, they had 170hp!” Once I got my G Body and starting learning about them, I didn’t sit and cherish it from a rarity standpoint (of course I did for centimental value). No, we swapped another engine and trans in, and i started building what I had in mind.
Looking back on it now a G Body was just realistic for me. I can never see myself owning a '70 Chevelle, but I can see myself owning a Trans Am GTA or other 80’s “performance car.” These cars just seem realistic and doable for a lot of people. And in a lot of cases, parts are still plentiful, so you don't have to worry about driving/beating on them.
Honestly G Body's are the perfect compromise, not rare enough to really worry about (in most cases, obviously the exception with the rarer models), but you can still have that "classic car" aspect, where people look at the car and go "wow!" just because they don't look like any modern car.
No offense meant here, but I think a lot of people fail to realize what these cars really were. The Monte Carlo SS, 442,
Hurst/Olds etc. were just "left overs" from the successors that came before them. They had big shoes to fill with those name plates, and in my opinion didn't come anywhere close to filling them. But that was just a sign of the times, and you had to pretty much settle with these cars. With the exception of a few models, the performance era was over at this point. The base models were average cars for the time, in my opinion they still weren't anything "special" or revolutionary, they were just following good selling market trends.
The collector market is pretty strange honestly. I have no doubt that G Body’s will continue to go up in value. But I think it will only be because you simply can’t find them anymore, or because of the nameplate carried on from older models.
To make a long story short, I think a lot of people over hype these cars just because of the name plates, or the fact that owning the previous successors just isn't realistic for a lot of people. This may seem like I actually hate the g body, but I don't. They are decent cars, but in no way shape or form are they the holy grail like they are sometimes made out to be.
