I would say there is not that many unrestored cars out there. first gen z/28 cars got used and abused by most, and finding a true matching numbers car is a find these days. You can put the sale on hold while you look at other cars, as long as you won't regret it if it sells to someone else. When i bought my car I wasn't going after a car with all the options. I wanted a unrestored Garnet Red (no vinyl top) Z/28. My car is late build (08C) car so it does have a tach, and the D80 spoiler package as dictated as standard equipment at that time of the year when it was sold. The owner did order it with a cowl hood, but other than tinted glass and a AM radio, it doesn't have many other options to speak of. No console, RS package, power steering, or X33. Which is fine with me, because it reminds me more of a strip special car, just the basics. So buy the car you want would be my advice, not the one you think others will want in the future.
