Well, for $7k under 75k directly from a Chevy dealer is looking good. You can ask them to give u an extended warranty at no charge.
I did look another car similar yr which had trouble selling - I test drove and there was no issue other than when the charging is interrupted it throws a CEL. Some gen 1 had these issues.
On the other hand, a car parked for 6months could cause issues like what they had (battery replacement). Usually dealers send a car to auction if it stays in the lot for a long.
I paid just over 11k for 2014 with 60k - price is good and they repaired it - ask for an extended warranty without charge - be prepared to compromise.
