I honestly don't know if Aaron is telling the truth or not, but he is correct in stating that this same vehicle with the exact same photographs & description was listed on eBay several months ago. I believe it might have been listed on other websites, too, about that same time.
Compared to either the 1989 SSC or 1993 SA-10, I don't really care for the SA-15 or SA-20. There wasn't enough of a differentiation between the latter two anniversary editions & the standard S281SC, other than the paint schemes, to make them desirable IMHO.
