I can't believe you blokes are being sucked into the Chev/Frodo argument again - by a self confessed "newb"!
John, have you got a budget in mind? If buying an unregistered car have you factored in $1500+ for engineering, nearly $1000 for first rego and RWC test, $1000s for stamp duty, custom wheels, etc? This exercise might help clarify your entry point and how long you have to finish the project. Will you be doing much of the labour yourself or paying someone to help you?
