My buddy owns a shop and loves Ford. They keep him in business! I'm not being funny, I'm serious. Caddy's are made like shit, but don't have as much maintenance issues. I had a Dakota w/ a 318 and had good luck untill I had to go to a dealer for a warranty claim. Had bad luck w/ 3 different dodge dealer over the years.
I was in charge of fleet vehicles for my family company years ago. Best luck I had was Chevy for trucks, Chevy and Jeep for sport uts, and had good luck with Dodge minivans.
Just my .02
