Here is my opinion--
I am 52 and have been doing this since I was 19. As several have said, you probably need to look at a lot of cars and talk to a lot of people before buying anything. When you are excited and new to this, it is easy to buy something quickly that is not the best for you. Restoring a car is a much bigger and probably a more frustrating job than you can realize until you do it.

I urge you to decide what you want to end up with--a nice car to drive?--a true matching numbers date code correct car to show? You probably want a stock looking nice car to drive on weekends that may not have all of the original drivetrain. In any event, you will be better off in every way if you buy a complete car in good condition to work with. Cars needing a lot of repair are too much for most anyone except experienced body guys. And taking a rusty car to a good body shop will probably cost you more than the car is worth. Spending more up front is almost always smart.

I would suggest a few car shows--especially Pontiac shows. Speak to a few of the car owners. Some of them will enjoy helping you and even look at a car or two with you. Every model and year has certain things to look for. I think you will be glad that you took your time in the end. This hobby can be the most fun or the most frustration that you can imagine.

You might start by contacting the POCI chapter in your area. They may have a car show coming soon or a meeting where you could speak to a few people.

Also, I am in the Triad area of NC. If you ever come this way, let me know.

Good luck!
Michael
