Testimonials

On 6/20/2026 Amanda Wilkins had this to say:
Unfortunately our diesel F250 truck broke down on our vacation. Supreme Diesel was easy to contact, easy to receive our towed vehicle and easy to work with. Nick and Victor were great! They kept us up to date and explained to us what was wrong, the necessary fix and an accurate estimate, which was very reasonable. Highly Recommend!!

On 6/11/2026 Dean Altizer had this to say:
Honest and helpful

On 5/27/2026 Thomas had this to say:
Ok this first review is just on first phone call about pre-purchase inspection. Nick seem to be very professional and knows what he was talking about. They very useful information about where to look for a used truck in the south. Gave thorough explanations on what they do for inspections and if stuff needed to be changed other things I might need to be changed with it to save money in the future. If I happen to find a truck in their area they definitely will be getting my business.

On 5/21/2026 Rodney S. had this to say:
For only being the Ford F250 Diesel shop within a 20 mile radius they are very reasonable and very very professional. I am so glad I found them.

On 5/1/2026 M T had this to say:
First time bringing our Ram truck to Supreme Diesel Performance and we’re really impressed. Victor and his team was knowledgeable, professional, efficient and honest about what needed to be done, communicated clearly, and they got everything done on time. No upselling or pressure. Just solid, reliable service. Glad we found this place.
