Mopar. Used to be a GM (Government Motors) fan but not since the bailout. Ford is a close second. Realistically, whatever is more convenient and less expensive.
Family full of fords here. GM made great vehicles but the bailout also turned me off. Dodge/Chrysler had some good years up till about the early 80's but then went cheap and they suffered. The newer gen dodges seem pretty reliable. Foreign wise Im a Honda man all the way. Cars, bikes, equipment cant be beat.
