Welcome, glad you found this site. First, EVERY Camaro has interest, because hardly any two 1st gens. are the same. Many feel the 69 model embodies the epitome of all the cars made in that era. It has beautiful styling, handsome from every angle, iconic to say the least. There were more engine options available in the 1969 model year than any before or since. Your car could be of particular interest as this site is always looking for authentic, original cars to document details and nuances that we all may learn more about the car. early Camaros have been the favorite car to modify and butcher. Many have been made race cars, street rods, restomods, and everything in between. Clean unmolested examples are scarce and the exception, not the rule. so your about to be purchased car has much to celebrate if it has made it over 50 years without succumbing to modifications, or at least, not too many modifications.Most all 69 Camaros have lower fender rust where the lower part meets the door. Floor boards and trunks are also subject to rust as well as rocker panels and frame rails and shock towers (where the rear shock bolts to the trunk area) Front foot wells and cowl seams and lower windshield/dash are rust prone. Most concern would be any structural rust. So examine frame rails, rockers and where subframe bolts to body (subframe mounts are prone to rust, as well). All rust is serious and needs to be considered because it is all hard and expensive to repair (correctly). Because repairs can quickly exceed the car's value, be aware that repairing is more a passion and loss of use, money and time are factors that need to be considered. Much more preferable, if the car is basically sound, would be to just drive and enjoy and concentrate on preservation. You would be very surprised how well a 50 year old car with rust, bruises, ripped seat, but still in its original, albeit faded, paint can garner a larger crowd than a shiny refurbished car. Why? They are few and far between these days and the fact it is like a just found artifact creates a lot of interest at shows. Enjoy and preserve. And again, welcome aboard.
As an aside, you may notice the last car in my signature was a 307 car.
