Hi, my aunt is looking for a new car?

My aunt is looking for a new car as her current one was made in 2001 and is starting to have some problems. So, this is what she's considering, and I'd like to know which of these is the best:
Buick Verano
Chevy Malibu
Honda Accord
Hyundai Sonata
Kia Optima
Mazda6
Nissan Altima
Subaru Legacy
Toyota Camry
My aunt will most likely buy a new car, or a slightly used one. So, which of these would you recommend as the best of them?
