The 70 and 72 were nothing alike, I borrowed a friend’s 70 and loved it. I gor 21 mpg in mixed driving and it was soothe and good handling (for that time) so I bought a one owner 72 . Worst mistake of my life I got 12 mpg on the road (after a tune up) The car was sluggish,ponderous and limp. To change a tire I had to have a block of wood under the bumper jack and still could barely get the tire off the ground. I had to replace the dist. cap every year and I was using the best parts I could get.When it snowed the snow would blow under the hood and make the car stall so every snowstorm I had to take the air cleaner off and drive with a big screwdriver holding the choke open.
My first and LAST chevy.
