That depends on your usage

I bought a 2001 Buick century 4 years ago. It was owned by a very old man, so the mileage was pretty low. Of course the style is not popular. I got 33 mpg on freeway and 17-19 mpg local. The car is pretty reliable. The only problem I got was the oil pressure regulator, which I replaced it last year (easy to change, the part cost me $60).

I am not recommending anything to you. Just want to you to know you don't have to stick with camry/accord. It is always better to have more choices.
