On new sales chief Mark McNabb's to do list in 2008 — figure out what is holding back sales of the Titan, Nissan's pickup truck, and the Sentra, its compact car.

For Sentra, the issue may be Nissan's subcompact, the Versa, which could be stealing sales. Versa is a success for Nissan, on track as of press time to finish a close second to Toyota's subcompact, the Yaris.
