I look at it this way.......
If Chevy came out with a ONLY RED vette for 64, or if Ford came out with a ONLY BLUE mustang in 65, etc... would a car lover really paint those cars green and black? Sure they may look nice, but it's not what they are supposed to be.
Would a Vendo 39 look good with a embossed Pepsi logo? Sure... if ya like Pepsi, but it's not true to what the machine is....
A machine is only original once.... but a restored machine should be just that... restored to its natural look.
But that's just my opnion,........... what do I know.....
