BEWARE of this shady mechanics!! Took my car for a $10 smog. They told me I needed to change the o2 sensor, vss sensor, knock sensor, n check engine light bulb which $1280. They said drive it around till the computer resets. Several days later took it back passed smog but the speedo n check engine light came back on as soon as I left the shop. Took the car back couple days later at 4pm n they said too busy to look at it that day n to bring it back the next day. Brought it back the next day at 1100, n at 415pm they didn't when look at it n told me the same story. Brought it back the next day at 830 am, no calls the whole day so went there at 330 pm n got another sad story. They said the gear in the tranny is broken n causing the problem cost $800-$900 to fix. So why did it cost me $180 to replace the vss n the problem still exists? I declined for them to fix anything else. I drove the car to AZ to visit family n decided to have my bro-in-law look at my car. He pulled the vss n looked at the gears inside the tranny n not one gear is broken inside!! Either these guys is not real mechanics or they are professional rip off artists!! U HAVE BEEN WARNED!!!!!
