Great customer service and an amazing mechanic! I’ve been trying for months several places around the U.S to get my APU fixed and this gentleman came through! Right in time for the summer heat. He also took care of my shocks as well. Has affordable rates.

After some quote surfing I landed on 4K. Bought a car with little to know background. Zack ran a complete diagnostic and gave me a very fair price, even uncovered some problems to keep an eye on. Very honest and straight forward people. Just moved to Phx, found my go to shop.
