I just wouldn't do it in Coke because they did make a embossed Coke 33, similar to the 27.
I disagree. If you ever decide to sell it, Coke is by far the largest market.
A full restoration would be a poor investment but a paint job is easy to do on this machine. (All red with a white door insert looks good).
They are very small and have a unique vending system. If you could get one for around $750........... buy it and have some fun!
