GMC's are nice. I love mine - it is different. I see them a lot more often now though it seems...I guess because I look for them more so than the Chevy's.
Up unitl last year I had 3 GMC's.
My 1971 (which was my first vehicle), a 1969 GMC Custom, and then a 1951 GMC.
I wish I would have had the time and money for the '51, as it was a gorgeous body style and probably one of my favorite trucks ever, but oh well, I guess you just can't restore 'em all.
The only one I have left now is old orange...me and the wife agree to keep it around.
