My engine light came on and when I called about it I was told they would probably have to put my car on the diagnostic machine and then it was a guess as to what would have to be fixed after that. So I took it in and left it, worried that I was going to have to spend a couple of hundred dollars on it right before Christmas. Then I received a call saying it was ready and there was no charge because they tried something before putting it on the diagnostic machine and it was fixed. Thank you, Courthouse Automotive, for making the season that much happier for me!!
