On the GM vs Ford, the Fords were not the new model. GM used the model before the upgrade. Autoblog or someone had a behind the scenes on the test and disregarded it. I don't perfer one over the other. I looke for condtion and what I need it for. You see less older Dodges because Chevy and Ford were making 400k or more a year and Dodge was 65-75k a year. Having worked at a Chrysler dealership 17 years, rust was never an issue. The tranny issue came up after the put the overdirve unit on the trans and put the pawl gear there. Took a bullet proof tranny and messed it up. Check issues with any brand you consider, Dodge for instance from 94-99 check for coolant leak (nr1 or nr8 missfire) caused by poor metal casting allowing coolant to leak through the heads onto the plug wire. Also check oil consumption, plenum gasket leaking oil inside the engine. I sure if you check Chevy and Ford has things to look for like the 4.3L vortec with nr3 on the crank ground wrong allowing a knock that was only repaired if the customer complained. I have a Chevy because I was owed a few thousand dollars and I gave the man 3k in credit for what he owed me. But, I really like the Suburban.
