hard to tell because the never showed a good shot of it, but in the carwash episode (get the dodge out of hell) it looks like a 70-71 duster
red, but resprayed, the trunk is brown
that episode is full of good qoutes about the dodge
al: oh, racing stripes
peggy: the dodge does not need a racing stripe, it couldnt hit 60 if you dropped it out of a plane
al: no but you could
al: that dodge is a finely tuned precision instrument , i dont want some strangers rough hands all over it
car wash employee: sir, we need the keys
:al reaches in his back pocket and hands him a screwdriver
kelly: hey daddy, im afraid i got some more bad new, i thought i'd check the lost and found...
al: oh, this oughta be good
kelly: there were no dodges, the was a nice plymouth though
peggy: oooh, al
al: i dont want a plymouth peg, i want my dodge, dagnabet
manager: dagnabet? what did you do, get the hooked on phonics: josemity sam tape?
after they loose the dodge, the carwash tries to offer all a new car,
manager: how does a new hyundai sound?
al: like an old lawnmower
