OK maybe we need to put this to bed..... First of all I'm NOT defending or attacking either position. Point of fact, in the late 60's early 70's it took upwards of 5 years to develop a car from scratch. Both vehicles in question are "clean sheet" designs. They were started around the same time, however Chevy also developed the engine, that's why it's entry came later. (I'm trying to avoid using veg@ cause I' don't want it to add "inferior") Cars of this era look just as similar as cars of the early 70's. Any similarites are PURELY CO-INCEDENTAL. The stylists had all the same influences & did all the same drugs. Though I wish they hadn't shared those with the engineers! It's just dumb luck that both cars had (at least later models) 140cu in overhead cam engines.
I've owned BOTH. I had a '75 Astre wagon (pontiac clone of the chevy) it was a GREAT handling car, however, like the '75 Pinto it was underpowered. Mechanically the two cars are very similar, as is my opinion of them. My brand loyalties run to Ford or I'd own a Veg@. Fords have just been better to me than GM. I've got friends who've had terrible luck with Fords & so swear by GM or Mopar. You know the old saying about opinions & bellybuttons. Everybody's got one.
Again I'm not trying to defend OR attack anyone, just set a few facts straight, to end a debate that could go FOREVER. I know some of us bleed Ford Blue & a few of us bleed Chevy Orange, but the plasma that carries it is PURE 10W-40. A little good natured rivalry is a good thing, however this looks to end in bloodshed & bad feelings.
