As for a 6 ft person sitting comfortably, it's a toss up, either the driver AND the person sitting behind them are 5' 5" tall or shorter, one is going to lose out in the seating catagory LOL!! I'm 6' 4" and I have to have the seat all the way back, the only person who can sit behind me, comfortably, is my 3 year old son, in his safety seat! LOL
The 1900 Wagon is "plain Jane", if you look in the for sale adds you can see a green 72 for sale. The "Sportwagon" was 74 & 75 only, they had rally wheels with trim rings and the interior was just like the manta Rallye, tach, extra gauge pod, thick "sport" steering wheel and fat shifter knob.
