Had an issue last Saturday with my truck, missfiring plugs is what it sounded like to me. Checked the codes and it was showing a P0300 which it was. I could change the plugs myself but as I was looking around the engine compartment I notice 2 broken exhaust bolts on my 04 Avalanche. Called Prestige and got an appointment the next day. They fixed the broken bolts on the other side of the motor when i originally purchase it 4 years ago. Which were still looking good. The last time I was there was when I bought the truck and they gave it a pre-inspection look. It helped me negotiate a lower price and I've enjoyed the truck ever since. This time they remember other issues I couldn't afford to fix at the time and reminded me about these issues I completly forgot. I said go ahead, fixed them all. In a couple of days I was back on the road. Truck was clean when returned to me and running strong. Than you Andre, Stephanie and Prestige staff. See you next time!
