It depends on what you mena by garage built. Is ordering a chasis, but doing the engine, plumbing, body, and major fabrication couted?
Where do you draw the line on what is garage built?
I would consider my uncle's '32 coupe a garage built car even though it sits on a TCI chassis and he had a local guy build some seats for him. He assembled it, cut and bent the plumbing, built the motor, fabbed the body mounts, brackets, and covers, the chop and section was done in a friend's garage, and the body work at another friend's garage.
