Everyone I dealt with at Zia was very kind and helpful. they diagnosed and replaced 4 spark plugs and one ignition coil to prevent cylinder misfires. They never tried to push any of these repairs on me, only stated the problem and suggested a course of action, leaving me the freedom to decide what I wanted to pay for, without any pressure that i've found at other auto mechanics who just want to make a few more bucks. The people at Zia just genuinely wanted to make sure my vehicle was running as best as it can, while cost was a secondary issue.
