I drove 50's GMCs when they were new. They are fun to drive, but require a lot of maintenance. And of course now you may or may not be able to get the part on the day you need it. And I don't think any one is satisfied that they are finished. I have 7 old GMC's and 3 1956 Fords like I was driving when my wife and I were dating. I would never want to depend on one of them to get me around town every day. I drive an 06 Chev 1500 and my wife drives an 08 Colorado. I plan on trading the 06 on an 09. I use my GM card enough to where I always have the maximum they will allow. It costs me less than $3,000 per year to never let a pickup get over 3 years old. I average 18 mpg and my wife averages 25 mpg. You don't get that with the carbureted engines. My suggestion would be fix it up some and drive it for pleasure. but look at it as a hobby. If you need daily transportation, get a newer more fuel efficient vehicle.
