Very pleased. Shop owner knows his vehicles, and can fix the problems. My brake problem was diagnosed and fixed. My engine problem was diagnosed and fixed, which I may add was not done at the dealership. Thanks Mark, for another great job.

I have used Zenk Auto and Repair for many years, I have always gotten into the shop in a timely manner and work done is always to my satisfaction. Always bending over to get your automobile running and back to you in a timely manner, there are no complaints. I recommend my friends and family for a job well done.
