They were all aluminum. The Cosworth head was for the sport model - probably the GT. Cosworth was not that failure point. They were actually the better Vegas.
Supposedly at the end of the Vega run - the last cars were supposedly pretty good but the damage was already done.
The Cruze is the new Vega. Built by even greedier thugs than the 1970s.
The Big 3 never really grokked small cars. If you think about the Camaro and Vega, GM pretty much just shrank the Camaro.
I remember riding in the very back of a packed Ford Pinto, right under the window, ice in the road: “Don’t stop short, Jerry! (the driver).”
So he stopped short on I-70, we got hit in the rear end and I jumped out of that bomb on wheels like a jack-in-the-box.
I suppose with the Volt the danger will be a dousing with battery acid.
