The popularity of the Z/28 makes it the fastest appreciating of the Camaros, even Pace cars. Even with the high production numbers the Z/28 prices are rising faster than any other camaro built. I am not some biased Z/28 nut,This is a fact. The Z11 Indy convertible is my favorite of all camaros. I have also owned a one owner extremely well documented Z10. It is said that at least one Z10 left the assembly line with the 720 orange Houndstooth interior. A couple of Z10s have been found with the interior but proved not to be original. There is an experimental Z10 that was built with the LT1 350, multi stage kickdown Trans, rear differential cooler aluminum radiator, wheel wells and liquid tire chain, along with other rare or non production peices. This car is in Tulsa OK with a little over 40,000 original miles. Although not documented eye witness acounts say there were a few Z10s at Indy on track day. The Z10 is more than an SS/RS with an appearance package, it is a special car that deserves at least a small place in Pace car history.
