Rear end yoke (car part) locked up, causing the U-joint to break.
Piston connecting rod broke (thank goodness it was idling at the time).
440 cubic inch engine has 375 horses, but gets 11 MPG.
Solid car, built to last forever.
Can repair almost anything with a screwdriver.
Will run 14.7 seconds at 109 MPH in the quarter mile.
Not many around, so it gets A LOT of attention on the road.
Well 11 mpg is really good gas mileage compared to some muscle cars back then.
That's pretty impressive that you've owned this car for so long, and also that you had the foresight to realize that it was a car worth holding onto. It's hard to find a cooler car than a Plymouth GTX! I always dreamed of owning one ever since high school, but the stars never came into alignment and now they are out of reach in price. Enjoy it!
