A shame about how Carlyle has been handled, my local store was one that carried a pretty decent stock when the brand came out, and they were kind of my go-to for a while. You would think if anyone could disrupt the traditional tool truck model for professional techs (we bring the tools- including warranty replacements- to you) it would be Napa, since they could use an "order online or over the phone and our delivery drivers will bring it" model that would provide a lot of the benefits of tool trucks without as much overhead.
One thing I have noticed which might be indicative of Napa's priorities is the tool sponsorship on Ron Capps' Napa-sponsored funny car. Most NHRA teams (in the fuel classes at least) have some tool association since it is quite tool-centric (between round teardowns, etc.). When Napa rolled out Carlyle, there was significant Carlyle branding on the car- a good chunk of the rear spoiler sideplates, which is reasonably valuable real estate. After several years, the Carlyle logo was still there- and presumably Carlyle tools were used in the pits- but became substantially smaller, closer to contingency sponsor size. Then in 2021 (I think) Carlyle disappeared completely and GearWrench was the tool sponsor, with a fairly prominent presence on the spoiler side plates similar to how Carlyle was in the early years. As far as I know this has continued to the 2023 season.
