2008 Nissan Altima Hybrid Sedan 4dr Sedan (2.5L 4cyl gas/electric hybrid CVT)
A very satisfying choice!
 I've had my NAH for 3 months, and I'm loving it.  I drove an Acura TSX before, and the Altima is not as much fun, but it has plenty of pep and compelling driving dynamics.  I'm pleased with an average of 34-35 MPG, but I am driving like Grandma to get those numbers.  It's loaded except for navi: heated leather, Bose stereo, blueto.   This car is a lot prettier than a Prius and is more fun to drive than the Camry Hybrid.   The interior layout is excellent: controls are easy to read and to reach, and everything feels carefully designed.  The modest rumble that you feel/hear when the gasoline engine kicks in does not bother me at all (some folks seem to mind).  All in all - great car!
