I hear where you're coming from Marlin. I'd be curious to know how the JL-8 option would affect the value on a non-performance oriented Camaro, say just a plain 327 car. Would the JL-8 option alone make the car super desirable, as I'm sure there were probably way more SS cars and Z/28s that got the rear discs, making the plain janer even more rare and unique, but I don't think the JL-8 alone would make an otherwise ordinary Camaro fetch extraordinary coin. I think it's more of a frosting on the frosting kind of thing. It will add more value and appeal to a car that's already got alot going for it than it will as a rare stand alone option in itself. I think the same can be said for the endura bumper. It's often regarded as a "performance" option as well. I think an endura looks cool especially on certain colors, and generally speaking it makes any given Camaro more desirable, but how many performance oriented new car buyers actually considered it a "performance" option in '69? To be honest I think an endura probably weighs as much or more than a standard chrome bumper. I guess when it comes down to it, it's just a matter of personal preference. Do you want whoa, show, or go?
