Testimonials

On 3/7/2026 Justin Klan had this to say:
This shop is a hidden gem, Jonathan is such a great, personable, and communicative shop owner. His shop was clean, his team was thorough, and there was no surprises (aside from the shock that I needed a new engine). My 2015 Yukon started making a loud tick/tap. 6.2 L86 engine had a bent pushrod. Unfortunately a previous shop had went to aggressive in cleaning the head and engine surface when doing another head gasket, leading to coolant leaking into the crank case. Instead of just slapping it back together and shipping it he did an oil analysis and along with other factors didn’t make sense to repair and rather opt for replacement. Jonathan dealt with the dealer, timeline was hit, and it was clear when I popped the hood the quality of work his team does, every bolt, cable, bracket ect was in place just like the factory. Aside from the shiny metal block, you would never know the motor was not original. Keep up the great work and my family extends a huge thanks for breathing new life into our family hauler!
