 My 10 yr old Nissan Altima is one of the best cars that I have ever owned, and I've had quite a few over the years before I bought this.  This car has been really good to me and the repairs have been very minor and only in the last couple of years...things do wear out after all.  The body has held up really well too; no signs of rust and it still looks nice.  If I were to replace it, that would be because I'm bored and want something new (this is the longest I've ever kept a car.  I used to get a new one every 4-6 yrs).
