I took my Duramax in after trouble codes appeared beyond by ability. Super service and options were discussed with me, along with pricing and timeline. Work was finished earlier than expected, and I could not be happier. I was referred to them by a trusted friend, and I will be glad to use Certified again if I need work... read full comment
