From "Registration Requirements for Home Made Specially Constructed or Kit Vehicles".
"NOTE: A motor vehicle bond is required when proof of ownership cannot be obtained for parts valued a $5,000 or more."
SCPN is for registration/title.
SB100 is for emission.
DMV handles the paperwork and fees for registration/titling.
CHP verifies the VINs (engine, transmission, body).
Brake and Lamp Inspection is just that, for the Brakes and Lamps.
BAR handles the emission testing/VIR/SB100.
DMV recommends this order CHP, Brake and Lamp, and BAR.
