2001 Nissan Altima Sedan GXE 4dr Sedan (2.4L 4cyl 4A)
Horrible mistake 
 I bought this car after my very reliable Buick Skylark bit the dust.  I'd owned an old Honda Accord (1990) before and thought I'd return to a Japanese sedan after growing up in Datsuns.  A Datsun, this ain't...  Instead, it was a horrible mistake.  In the span of 1 year (2009), I put front brakes/rotors, exhaust/muffler, an intake manifold gasket (INCREDIBLY expensive repair for a $10 gasket-- $750), a battery, and an oil pan gasket and oil sender unit.  I literally poured over $2500 into this car, and that's without my boyfriend helping me out, as he sells parts for GM and could do some of the repairs independently.
