** The GMC repair market in the Iselin/Woodbridge area is competitive and diverse. The quality of service providers ranges from quick-lube chains with limited capabilities to highly specialized independent shops and the dealership. The average quality is good, with several shops demonstrating deep, brand-specific expertise, as identified above. **Competition Level:** High. Residents have access to numerous independent garages, a large number of general repair shops, and the presence of a major GMC dealership (Carlo GMC in South Plainfield). This competition benefits consumers by driving a focus on customer service and specialized skills. **Typical Pricing:** Pricing is mid-to-upper range, reflecting the northern New Jersey cost of living. Independent specialists typically offer rates 20-30% lower than the dealership while often providing superior or equivalent expertise for complex mechanical issues like diesel and transmission work. A standard diagnostic fee ranges from $120-$180. Major repairs, such as a Duramax injector replacement or an Allison transmission overhaul, are significant investments, often costing several thousand dollars, but the specialists listed are known for providing fair and transparent quotes.
