Our Expertise

Owned and operated by Karl Trevett, our journey began with an apprenticeship at a Honda dealership, where NVQ Level 3 qualifications and an F-Gas certification for air conditioning were achieved. This was followed by five years at a Mercedes dealership, gaining in-depth knowledge and earning recognition as a Mercedes Systems Technician.

Further experience was gained at REPerformance, an independent supercar specialist, working on some of the world’s most prestigious brands, including Ferrari, Lamborghini, and McLaren. This provided invaluable expertise in luxury and performance engineering, along with a meticulous approach to precision and detail.

Why Choose Tri-Tec Automotive?

Originally launched as a mobile Mercedes/AMG specialist, the business quickly expanded, leading to the opening of a dedicated workshop in 2025. The focus is solely on Mercedes cars (not vans), with services including:
