After about 5000 miles on a truck that rarely gets driven (this took about 2 years to accumulate), we started having issues with the coil packs installed at C&S tire (surprise! See my review on their "work" on our other vehicle). Anyhow, Auto Fitness was able to put new spark plugs and coil packs into the truck in spite of the shoddy tap job done on one plug at C&S. The cost was a bit steep but in general we are pleased with their treatment of us, and will again plan to use them next time we are in need of car service. A good mechanic is hard to come by and an honest one even more so.
