Master Care Auto provided me with great service that was timely and professional. Honest and affordable the words I would use to describe MCA. I appreciate seeing photos of the work being completed. Sandy, Ruben and Oscar have provided a positive experience. I would recommend them to anyone looking for reliable, affordable service from friendly and knowledgeable technicians and staff.

I had been to two shops prior to finding Master Auto Care and all that happened was money veing flushed down the toilet, but Master Auto Care took their time diagnosed the issue, then solved the problem while maintaining excellent communication and customer service. I will recommend them to any and all who need vehicle repairs!!

if you like being in the dark about repairs and dealing with terrible customer service then this place is meant for you
showed up for my 10am appointment and had to wait 20+ mins since the receptionist wasn’t at her desk. when i walked across the street she was on her phone. i let her know how long we’ve been waiting and she just said “i’ll be over” without any apology. then had to deal with constant miscommunication on how long repairs would take and would go days without any updates. even when the car was ready i was only given 1 hour notice to pick up or it would have to stay there for the weekend.
