Having just gone through a search and ultimately the purchase of my '72 tii, I have to say that the Hemmings estimates lag the reality in the market today. First, few folks are selling, so supply is even more of an issue than it is just by virtue of the small number of remaining "good ones" out there. Recently, an Inka '72 sunroof car that was originally from CA was listed on this venerable site and sold quickly at full price, which was $32,500. That was NOT a fully restored car, but rather a survivor with some mechanical and cosmetic freshening.
Second, what few cars I did find that were for sale in the West were north of $30K, at least one being north of $40K (and that one was a square taillight car!). I looked at an original, survivor early '72 tii, no sunroof, but long term ownership in central CA. The owner had no intention of selling it and he told me that he turned down $35K just last year. The guy had a car collection in his barn that very clear said he didn't need the money.
I appreciate that this may sound somewhat self-serving, but I think a good, straight, original tii is a $30K proposition all day long and probably more, and if you happen to own a car like that in a desirable color, with clean interior and solid mechanicals, I think $40K would not be outlandish to ask, with the expectation that it will take a true enthusiast or collector to step up and pay that.
Paul, I have never seen your car in person, but based on the photos of it, I think $30K would be an absolute steal and could be low by $7500, not that it's actually for sale!
