To sell right now realistically
around $27,000 but again like yours maybe a bit more to the right buyer.
(My insurance policy has an agreed value of $35,000 for my 911)
The problem with local 911s is that a lot of them have been "molested" and as you know that always has a detrimental effect on value.
Someone is asking $34,900 for this 1977 Porsche 911.

This is a little more interesting. A LHD 1965 Porsche 356C $70,000 (but personally I wouldn't buy a LHD)
