Regardless of mfr. the most important thing in buying a 9+ year old car will be previous history - is a service history available? was maintenance performed/on time? were most common high mileage issues fixed? ...better again if you know the owner and can get an honest answer.

...to answer your other question about dealership, either be willing/able to do the work yourself or find a good Indy........do not go to the dealership for out of warranty repairs unless you have deep pockets.
