[1969 GMC]

well newer SUV's are like that...the bench will be about a 60/40 split and the smaller part will fold back, and there are doors on both sides. i think the real reason GM didn't design a 4th door until '73 was because it saved them money on each unit produced. sure, it helps keep passengers out of the road but IMO that is a stupid reason. if it is so safe then all the suv's now should have 3 doors, but having 3 just makes it that much more impractical. also how many burb owners do you think parked by the curb all the time? this is stretching but still. bottom line: it saved the general some cash.
