With a rating of 4.7 from 66 reviews, Tripp Trucks earns high marks for its knowledgeable staff and prompt service. Reviewers often highlight their efficiency in diagnosing and repairing diesel issues. This shop is best for those seeking reliable service without long wait times. However, some customers note that busy periods can lead to delays.
Supreme Truck & Trailer Repair holds an impressive rating of 4.8 based on 26 reviews. Customers appreciate their fair pricing and quality workmanship. This shop is ideal for budget-conscious drivers needing solid diesel repairs. However, the limited number of reviews may make some hesitant to choose them over more established options.
With a rating of 4.8 from 22 reviews, Interstate Fleet Services LLC is noted for its thorough inspections and effective repairs. Clients often commend their attention to detail and strong communication. This shop is best for fleet owners needing consistent service.

Neal's Repair Service has a perfect rating of 5, but with only 6 reviews, it remains a promising yet unproven option for diesel repairs. Customers appreciate the personalized service and quick turnaround. This shop might appeal to those looking for a small, community-focused business. However, its limited customer base makes it harder to gauge reliability.
CARRS holds a rating of 4.4 from 85 reviews. Customers often mention their comprehensive range of services and knowledgeable mechanics. This shop is good for those needing various diesel repairs under one roof. However, some reviews indicate that wait times can be longer than expected during peak hours. That is a substantial body of feedback for a local operator, enough to trust the rating rather than credit a lucky streak. Most of what reviewers hire it for is variety of diesel repairs. It serves Rock Hill, SC, with $90 to $250 pricing, and the honest trade-offs are longer wait times during peak hours.
State Line Diesel Performance LLC also has a 4.4 rating, backed by 69 reviews. Reviewers appreciate their performance upgrades and tuning services. This shop is ideal for those looking to enhance their diesel vehicles. However, some customers have mentioned inconsistent service quality, which can be a concern for regular maintenance.
Rock Hill Truck and Trailer has a low rating of 3.7 from just 3 reviews, suggesting it is still building its reputation. Customers appreciate the friendly service, but the lack of extensive feedback raises concerns about reliability. This shop may be worth considering for minor repairs, but caution is advised given the thin review base.

This business is best for emergency towing needs. However, if you're looking specifically for diesel repair, you may want to consider other options.
