Hi Nolan,
In my opinion, you have quite a gem there. I am lucky enough to be the current custodian of the SAS Cab built for john Eastman.
You have a very rare car that, to the right person, is worth what you have it insured for. There aren't many Cabriolets available. I love the extra windshield height, and mine has a ton of leg room as well. I'm 6'2" with a very long torso and short little legs, so my head sits about the same hight as someone around 6'4" when seated, and I have plenty of headroom with the top up,
