I'm either the 3rd or 4th owner, but not sure. Looked at the title just now, which I thought might give me an indication of the number of prior owners, but apparently not so. Purchased mine in 1996 with 66K miles, and have had for the past 26 years, and now a little over 132K miles.
I agree with Top Down. Similar story with the current muscle cars - see lots on the used car market, especially the Camaro and Challenger. Original owners found out how impractical they were and unloaded them. The 2nd and 3rd buyers, like the Reatta, were people who had more of a fondness of the vehicle and cared less about practicality, and who retain ownership for an extended time.
