I have to say Ford even though I will never buy another one - the local dealer and Ford Motor Co. screwed me over several years ago. It was over a measly $500 rebate, some things I don't forgive.
This is a hard one for me. My grandpa was obsessed with Fords, so they're sentimental to me, plus there's a lot of Ford types that I like: the GT, the Bronco, and the Ranger (Raptor). Then on the Chevy, it doesn't have the sentimental attachments to me, but there's still Chevys that I like, like older, box-body Blazers, and the Suburbans and Tahoes.
I'll probably have to choose the Ford, even though some of the Chevys might serve me better than a Ford would.
