Why These Are the Top Hyundai Repair Auto Repair Shops in Thornton

** The Hyundai repair market in and around Thornton, NH, reflects its semi-rural New England setting. There are no specialized, "Hyundai-only" repair shops within Thornton's immediate city limits. Consequently, residents must look to the surrounding commercial centers like Plymouth, Tilton, and Laconia for quality service, with the primary Hyundai dealership located in Concord. * **Average Quality:** The quality is bifurcated. The dealership (Grappone) offers the highest level of manufacturer-specific expertise, particularly for warranty and advanced electronic systems. The top independents (AutoServ, R&S Auto) offer excellent mechanical repair quality, often with more personalized service and lower labor rates. * **Competition Level:** Competition is moderate. The dealership holds a monopoly on certain warranty and certification-dependent services. The independent market is competitive on price and customer service, with the most successful shops having long-standing reputations. * **Typical Pricing:** Pricing follows a standard tiered structure. Dealership labor rates are the highest, typically ranging from $150-$180/hour. Top-tier independents like AutoServ are slightly lower, around $130-$150/hour, while smaller, highly-rated shops like R&S Auto may be in the $110-$130/hour range. For specialized services like GDI carbon cleaning or DCT fluid service, parts and procedure costs are significant regardless of the provider.
