Paul,
I took a look and low retail @ $10,375, Mid @ $17,550 and high @ 28,675 sounds reasonable to me. I recently saw one for sale here in NE Ohio for $19,000. It was a mid range car. I will point out that it has been around for a while at that price with no takers. Also I might mention that to bring this car up to high would most likely require up to $20,000 if professionally done. Then one would have nearly $40,000 invested. I have seen quite a few 40K TR250's out there.
