No one knows but you can postulate that it couldn't get out of the shop?

For the C6 it was more like 50 "X" cars that were road tested and then
destroyed. Those with an "X" in the serial number plate can not be sold.
There is a picture of a silver one in the CAC history with me sitting in it
6/3/2004 at the first National meet. My first model year has been that way,
every time I turn around it need gas, and then it's tires again. Then there
was the, oh wait there wasn't anything else except the AHC recall (no cost).
So much for your first year antiquated theory, you need to get into the 21st
century. Then there is your advice to not buy a new car when the C6 had a
lower base price than the C5 for a few months then went up, saved me a bunch
and I was driving my car not something someone else discarded.

So what's your opinion of why Fisker Karma chose GM's engine to put in the
most expensive car built in the most expensive state with the highest tax
rates and most subsidized people and companies in the USA? Could only be to
keep the negative KARMA going.
