I prefer Toyota cars, but my "evidence" is only my experience.
I've owned mid-range and economy cars, a Ford Tempo and a Ford Escort. I drove both well over 100,000 miles, so no complaint there, but they were a constant source of "things" going wrong, ranging from fuel pumps to brakes to door locks to automatic seat belts to blah, blah, blah. It seems like about every 3 months there was a $200 bill for something or other.
I've owned two Toyota Corollas and a Toyota Camry. Very comfortable cars, also drove them well over 100,000 miles. Had only one minor repair done on the Camry.
It's hard to imagine every buying another Ford, but I would definitely buy a Toyota.
(Trucks are another matter altogether. I've had Dodge, Chevy and Ford trucks for work, and found the Ford trucks can really take the punishment and come back for more. I much prefer the Ford F-series truck over any comparable vehicle.)
