A son made his Dad a promise that he said he would keep by his father's 57th birthday. Easy right? Not when it was to buy his Dad's "dream car". For years, his dad talked about always wanting to own a 1957 Chevy. When the son was only 8 years old, he told his Dad that he would buy his dad a '57 Chevy by his 57th birthday. A promise the son kept. His Dad's reaction? Priceless.
