On my blue Vega below, between my dad and I we put over 93K on it. The only things that ever went bad were a throwout bearing and a starter drive. Oil was changed like clockwork and car maintained to the max. I found my used Cortez Silver Yenko Deuce at Broadway Chev in Green Bay and was going to trade the Vega in on it, but my dad wanted the Vega. Later, my brother stuffed a SBC in it and the last I heard it was still on the streets in Green Bay.
