Matthew, welcome to TC! Always good to see the new generation of Camaro owners starting up, considering it seems like most guys your age seem to be into the imports.
You will need to give some hard thought to what you want to do with the car, and your budget. If you're thinking a 70s Camaro, that is what we would call a 2nd gen.
1st gen - 67-69 models, available in both coupe and convertible (vert) models.
2nd gen - 70-81 models, coupe only (t-tops in waning years, but those can be pretty leaky); 2nd gen further divided into "chrome bumper" (70-73), "big bumper" (74-77), and "soft bumper" 78-81. Excellent info, including another good, responsive forum, can be found at: http://nastyz28.com/
Not, trying to run you away from here, because this is a good group of folks and many 2nd gen owners belong here. Just making sure you get all the info you need/want.
3rd and 4th gen - 82-92 and 93-02.
It still remains that 2nd gens lag behind the 1st in popularity and pricing, which is good if that is what you like. Good, solid 2nd gens can be bought for less (sometimes half) of an "equivalent" 1st gen. 2nd gens were a huge leap ahead in handling and refinement, and can be a blast to drive.
Once you start identifying potential cars and plans, feel free to post up here and ask advice. Lots of us will look over pics and offer opinions/advice, and once you get serious about a car, you may find a member here that is local to you and can provide another set of "expert" eyes.
So, if you want, tell us which particular years of cars you are thinking of, and maybe we can find some examples to start discussing.
