I bought an new Olds diesel, the year eludes me now, and it ran for 27 miles before crud screwed up the injection pump. After a rebuild, it ran for about 35K miles and required another repair to the pump. When it ran, it was a nice car. I subsequently bought a Honda Civic which I put 359K miles on. It also got 40+ mpg so it paid for itself in fuel savings.
Last month the Civic was the best selling vehicle in America. GM has nothing that can compete with it.
