Wow. I really like that color. Is that a repaint in original color? Can't recall if Cookie cutters were optional on the 912. They were available on same year 911s so it is certainly possible. The blue centers are neat accent.
Likely has 205/50 tires on those "massive" 6x15 rims
Any specs on the motor rebuild?
Mirrors, as noted are wrong (and technically so too are the amber taillights

)
912s are a pricing enigma given their 1) small quantities and 2) reduced performance made them a stepchild to the 911.
Not sure what emmission are like in CT for a 30 year old car. Maybe you can get antique/classic/qq tags and avoid the whole issue
Depending on the close ups and a PPI, I would guess $6-8k
