OP,
Of the brands being discussed two are American sourced brands and one is now a foreign brand.
BTW... My 6.7 Power Stroke has 140k miles and not a single issue with the engine as some here would like you to think. The engine/transmission is a very reliable drivetrain that's second to none. Maintenance work is very well thought out and changing the oil is a breeze and actually very enjoyable unlike that other brand that having to access a oil filter is ridiculous.
Perhaps the ongoing safety recalls on one brand is a sign of poor engineering and build quality.
Good luck with getting that Chevy delivered asap.
