General Motors's (NYSE:GM) stock is trading at just 6.3 times GM's expected 2017 earnings. That's well below the roughly 10 times earnings that we'd expect for a healthy automaker. And thanks to that modest valuation, GM's steady dividend is yielding 4.1% right now.

GM might seem like yesterday's news, a "value trap" set to be eclipsed by high-tech names. But some famed value investors, including the great Warren Buffett, think GM is worth holding. Are they seeing something that we should be looking at more closely?

Buffett owns GM, but should we?

As I mentioned above, GM's shareholders include some very big-name value investors: Warren Buffett's Berkshire Hathaway (NYSE:BRK-A) (NYSE:BRK-B) and Mohnish Pabrai, for starters.

It's not hard to see what those brilliant investors are probably noting. Yes, GM's stock is cheap according to those simple measures. But there's much more to it: Under CEO Mary Barra, GM has shifted far away from its longtime obsession with market share, refocusing on much more Buffett-like measures: return on invested capital (ROIC), credit quality, and the amount of cash returned to its shareholders.

GM's shares have been stuck in a rut for a while. I think they've been overlooked as Wall Street hotshots have chased hot names like Tesla (NASDAQ:TSLA). To be fair, Tesla's stock has delivered outsized returns -- at least so far.

But there's a good case for an investment in GM too, and it's only going to become clearer over time. As GM itself sees it, the investment case for GM stock has four parts:

  • "Disciplined capital allocation." That's GM's term for its investment approach. GM is committed to seeking ROIC of over 20%, while maintaining a cash reserve of about $18 billion, preserving its investment-grade credit rating, and returning all excess cash to its shareholders. That emphasis on high ROIC has led GM to exit less-profitable businesses, most notably by selling its European operation earlier this year.
  • Earnings growth. Thanks to that emphasis on ROIC, GM's profit has been growing faster than its revenue -- or put another way, GM's operating margin has been increasing. Strong new products have been especially helpful here, and GM's brand-new lineup of crossover SUVs should help sustain that trend for a while longer, even if the U.S. new-car market weakens.
  • Downside protection. Autos are a cyclical business, but GM is well-prepared for the next downturn, with a much-improved cost structure -- and that hefty cash reserve, which is intended to ensure that GM can sustain its investments in new products and technologies through a recession, when profits may be thin.
  • Technology. More than most traditional automakers, GM is out in front of the high-tech trends that seem likely to transform the auto business: electric vehicles, self-driving, and shared mobility. Tesla gets the big press, but remember: GM shipped its affordable long-range electric car months before Tesla did.

The big takeaway: GM is an intriguing buy

To sum up GM's own argument: GM is well-positioned to thrive, both in the present and amid the disruption that's likely to come to the auto industry in the near future. It's in a cyclical business, and a downturn could be on the horizon, but it's well-prepared to come out of that downturn in a strongly competitive position.

Meanwhile, as I noted up front, the stock is inexpensive by historical measures, and it's confident that it can sustain that nice dividend through a downturn (unless things get dire, of course). There's a nice story here, one that's already being reflected in GM's bottom line. I think a patient investor could do a lot worse than to buy some GM shares now, reinvest the dividends, and wait for Wall Street to catch on.
