Imagine if he had come on the HAMB and said "I'm going to scratch-build an 11/16th-scale '28 Chevy sedan from refrigerators."
Yup, Ernie Adams and his cars have been discussed here a number of times over the last 15 or 20 years...just do a search on 'Ernie Adams' or 'dwarf cars', you'll find some of the past discussions. He has a museum: https://www.dwarfcarmuseum.com
Well since they are all made from scratch(ed) refrigerators they would be customs. Neat stuff and great craftsmanship even though the Merc could use more of a slope in the roofline.
I met him at the Back to the 50s show in St. Paul some years ago. He had driven his tiny Merc from Arizona to Minnesota, he's a tall guy too. The car is even more impressive in person.
I would say it's hard to get my mind around something like that. But in this case, it'd be hard to get it around my mind.
