Because this project most likely will never be finished..
can the op afford to take on such a project? it would make sense to know this before continuing discussion
oem glass, door parts, lights, grills, hinges, interior, drivetrain, chassis, wheels, paint etc etc. haven't even been factored in yet
Not to mention it hasn't been done yet so lack of knowledge out there compared to building a g28.
Meanwhile we wait for the first watson kit to be built :S
