I would definitely expand my search to the KC and OKC areas. I have known of 3 or 4--one I know is owned and raced by an SCCA member. Another one was owned by a fellow employee who got transferred. Another was owned by a fellow employee who sold it when his wife had a baby. One other I see around Derby every so often, and I assume it's always the same one, but I don't know the owner.
I see more SVTs than early SEs around here. Somebody's got to be selling one eventually.
