I think its because we grew up with them and there in-bedded in us for that reason for the most part. I have owned many different brands in the past and certain ones stuck in my head for their style,performance,reliability,etc. GM vehicles have always been good to me in the past...one when we sold it-it had 479,000. miles on it and ran great same engine. I do like many vehicles offered by all the brands pretty much though.
