My wife has a plain 2003 Corolla (no packages, no power windows or locks etc).
And it's never had a real problem.
I do change the oil once in a while and we did get some new Michelin HydroEdge tires in 2008 and a new battery last year.
Standard stuff, batteries need to be replaced about every 6 years in this climate.
She loves the car, hates the manual windows. This car was made in Canada
and I guess a large batch of them had annoying rattles in the doors.
Not a big deal to me, being hard of hearing..
