2006 Nissan Altima Sedan 3.5 SE 4dr Sedan (3.5L 6cyl 5A)
Well-Built, Dependable Altima
 Replaced a '93 Maxima w/'06 Altima, and would do it again.  Only problem was replacing a leaking steering oil pump, under warranty, n/c.  Otherwise, just standard oil changes after 2+ years of ownership.  On one long-range trip, got 27.75mpg w/continuous ac use.  This car is well-built, stylish and inexpensive to maintain.  Plenty of power w/6 cyl.  Only real criticism: ease w/which the rear bumper can show scratches, scuffs -- just be careful!  Good visibility all around.  This is a great mid-size, mid-priced sedan.
