Zone Kar Inc at a glance

Customers frequently cite honest communication, transparent pricing, and willingness to perform free inspections or minor fixes as key positive aspects of the service. Reviews highlight efficient repairs for brakes, oil changes, and body work, with many noting that the shop avoids unnecessary upselling. However, a small number of low-star reviews report issues with misdiagnosis, alleged damage to vehicle components during service, and complaints that specific labor charges were higher than expected compared to other local shops.

Amazing amazing service! I made an appointment to get a headlight fixed and Murph was extremely accommodating when I asked for a last minute oil change, too!

The absolute best - we are fortunate enough to live in the neighborhood, and on multiple occasions Murph and his team have squeezed in my car and taken a thorough look. They are always kind, clear, and transparent. More than once they've explained the issue, or fixed it, at no charge (including recently, when they problem-solved our faulty jumper cables and got my car back up and running after hours). Mechanics can sometimes get a bad rap, but I cannot recommend the team here highly enough if you want to be sure you're getting high quality work at the best price.

Zone Kar completely changed my perception of auto repair shops. Instead of the usual upselling, vague explanations, and surprise charges, Mr. Tong was honest, transparent, and took the time to clearly explain exactly what my car needed and what it didn't. I highly recommend Zone Kar.

I came here last year after seeing someone's recommendation, and even a basic oil change turned into a disaster. My car is now leaking oil from the filter area; I took it to another shop and after replacing two filters, it's still leaking. It's pretty much certain they ruined my oil housing.
