Since the dot-com implosion, the business-to-business sector has come under much criticism. But that hasn't stopped DealerTrack (NASDAQ: TRAK), which has built a sophisticated lending platform for the automotive retail industry. It deals with more than 22,000 auto dealers and 465 financing sources.

Well, this week the company announced its Q4 results. Revenues spiked 33% to $60.7 million and net income was $4.1 million, or $0.10 per share.

Unfortunately, it looks like the company is decelerating somewhat. No doubt, the credit crunch is putting pressure on dealers, who are having more difficulties in securing financing for car purchases.
