Hard to tell since they don't come up for sale very often 1 of 24 car is hard to price. The TTA don't grab the value that a GN or GNX get, but I would hold out for at least $30k since there aren't many around. Depending on condition and all that stuff of course. Only 39 hard top TTA's ever made in the universe if you think about it. That makes them pretty darn rare in my book!
