Old Parked Cars is one of my favourite blogs. If you haven't seen it you should. (Look at the My Faves list on the left, and just click.)
I know this isn't a truck - but it's almost big enough to be one. I saw it today outside my office. The last great Oldsmobile - the 1983-84 Oldsmobile 98 Regency. (I hope the snow tires will not be needed soon.)
Oldsmobile did make trucks at one time, and after Ransom E. Olds sold the company he went on to found REO trucks.
