The 1975 930 would be very rare in the US. Europe perhaps, but not for sale in the US until 1976.

1976-1977 cars are spec'd the same, although options may differ.

15" rims (7 and 8 x 15) were standard (16"s not available till 1978)

They were 4 spd (all Turbos were until 1989)

HP? I've seen ratings of 260hp (euro) and about 234 (us) in various period correct publications.

3.0 liter motor. no intercooler.

small brakes (essentially the brakes from a 911 "S").

1978-1979 had a host of improvements and are thus the more sought after cars: they received 1) displacement bump to 3.3l (good for 300hp) and the addition of an Intercooler; upgraded "turbo" brakes; 16" wheels.

Not sure of value simply because few were made and even fewer survived without modification.

The first year Turbos were notoriously known for Turbo lag. You could almost count down... 3...2...1.. Blastoff!. Make sure you're pointed where you intend to be when the boost comes on because you will be there quickly.

Off boost, ugh. Seemingly no power at all.
