It's $10, Mr. Market? Seriously? For a leader in a wide-moat industry that earned $0.59 a share in its most recent quarter?

Knowing only those things, it sounds awfully cheap, even in this environment. Trading on Monday, Ford (NYSE: F) dropped below 7% at one point in the trading session. It traded below $10 for the first time in more than a year.

Of course, there are a lot of good companies selling at what seem like big discounts at the moment, thanks to the sudden gaping pit of economic uncertainty that opened after S&P's downgrade last Friday. Those looking for bargains have no shortage of interesting opportunities to explore.

But here's the question: Should Ford be one of them?

A steal? Or a justified sell-off?
Despite the fact that I own Ford stock and plan to hold it, it's not a simple question to answer, as I discovered early this morning when a longtime Fool (hi, Paul) took me aside at the gym to ask me exactly that. On the one hand, as auto companies go, Ford's in unusually good shape with another possible recession brewing:

  • A solid balance sheet. Ford still has around $13 billion of long-term debt left over from the mortgage-everything self-financed turnaround plan it initiated in 2006. But that's much less than the schedule called for, and meanwhile the company has amassed a $22 billion cash hoard. That should be more than enough to sustain product development through another downturn while continuing to fund expansion in places like China and India.
  • Great management. I can't say enough good things about the job that CEO Alan Mulally has done since joining Ford in 2006. Over and over, he made changes that longtime Detroit-watchers thought would be impossible, turning Ford into a relentlessly focused and unified global powerhouse with a solid financial foundation -- despite the worst economic crisis in decades. This company will be well-led through any downturn.
  • A low break-even point. This is a big deal. Automakers are cyclical companies, and for decades Detroit made big bucks during good times and posted losses during tough ones. But a drastically improved cost structure has meant that Ford has been solidly profitable during this very sluggish recovery. Even during the rough first quarter of 2009, Ford was close to breaking even before special items -- and the company's costs and products have improved further since then. That bodes very well for the company's chances during another downturn.
  • An enviable (and envied) product line. Auto companies live and die by product, and simply put, most of Ford's are now excellent. Defying the Detroit stereotype, Ford has leveraged its global organization to develop a series of genuinely class-leading products. That's a direct result of the huge borrowing spree Ford went on in 2006 -- thanks to that cash, the company was able to sustain its product-development programs during the downturn, when rivals such as General Motors (NYSE: GM), Honda (NYSE: HMC), and even Toyota (NYSE: TM) were cutting back.

Long story short: Despite that debt, Ford is probably as well-positioned as any global automaker to thrive during and after an economic downturn.

But here's the bigger question, the one I struggled with when talking to Paul at the gym this morning: Is this a good time to buy any automaker?

Would you buy a car right now?
All of the automakers on my watchlist took a beating yesterday -- Ford, GM, Toyota, even Tesla Motors (Nasdaq: TSLA) were all down sharply, just like most of the rest of the market, thanks to the acute sense that economic suffering lies ahead. Automakers suffer when their customers (including individuals as well as the corporate and municipal fleet buyers that drive about a quarter of Detroit's sales):

  • Put off purchases because money's tight.
  • Can't get financing because credit is being constrained.
  • Downsize to less profitable smaller vehicles because of cost concerns, or because of related factors like rising gas prices.
  • Skimp on options to keep the price down, because options like "infotainment" systems and luxury or performance packages have very high margins.

All of those things happen during recessions. While it's true that the current level of auto sales in the U.S. is still far below pre-2008 norms, those sales have been profitable ones for Ford. Many buyers have been downsizing, but they've been choosing profitable options packages like Ford's SYNC "infotainment" system for their smaller cars. That has helped keep Ford's margins strong, and that could be at risk.

Another looming near-term concern
There's another concern. Automakers also suffer when competitors boost margin-killing incentives (those "cash back" or "0% financing" deals), as they have to respond in kind or risk losing market share. Even before Friday's downgrade, auto worries were rising after Toyota executives signaled that the company will offer major incentives this fall.

Toyota's recovering after months of lost production due to the tsunami, and the company wants to re-establish its leading position in the all-important U.S. market. That means a sales battle, and while that could help get more recalcitrant consumers into dealers, it's likely to hurt margins for everyone. I wasn't too worried about this last week, when it looked like incentives might help bump up the overall level of sales. But right now, that looks less likely.

The upshot: Proceed with caution and open eyes
Ford's renaissance is still an unfolding story, and it's still a good one. And there's no doubt that it's cheap at today's prices, with a P/E around six -- though as I said, the direction of future earnings is an open question right now.

I am convinced that there will come a day when today's prices for Ford look like a bargain, and that if you buy here, you will make good money in time. But it might be awhile: Even if Ford remains profitable through another downturn, those profits are likely to look relatively skimpy by recent standards.

In the end, here's where I'm at: If you're willing to hold for a while, you could do a lot worse than to buy Ford. But right now, you might also be able to do better.
