Contacting GMC Customer Service Center
GMC is a brand of truck, van and SUV sold by General Motors. Larger vehicles have traditionally been known as gas guzzlers, but GMC is attempting to change that with hybrid trucks and SUVs. Some models offers double the miles per gallon compared to traditional models, but the price is nearly twice as high.
