Diagnostic services service near El Segundo, CA

Jesse and his team are top notch! I have been bringing my nissan altima to M&J for the past year and very happy with the work and attention to detail. 5 stars!

Not happy with this place or the work, took my M3 there one time, and that was all it took. First off I had plenty of work done, header install, carbon intake installed, water pump, coolant hoses, O2 sensors, thermostat, crankshaft seal, and instructed him to repair the oil leaks. Ed says he repaired my oil leaks, yet my car continues to leak oil, he damaged a $400 wheel, which he said, if the shop he knew, could not fix it, he would buy me a new one. When his shop failed to do so, I asked about a new wheel, of course he then said, he had no money to get me a new one, so I paid out of my pocket for a new wheel. I had him install my carbon air box, and he removed my OEM clamps, threw them away and replaced them with some junk hose clamps, stating he did not have the tool to replace the clamps, not sure what that has to do with me. So I took my car to check on the oil leaks and was told and shown by the shop, how the oil pan was not only missing bolts, but some were sheared off from over torquing, I was also missing header and sway bar bolts from his header install, my power steering hose was not secure, causing it to rub on part of the motor, damaging it, there were a few other things he failed to do, now costing me over a $1000 to repair after paying him over $2000 for less than subpar work. Do yourself a favor, and stay away.

I was in need of brake repair and looked here to find a shop with good references. I feel like I hit the jackpot. I called two days ago and made an appointment, then went in the next day. Steve took my car in right away, offered me a ride home, called me a couple hours later and said the car was done and sent his son to pick me up. The car runs just as good as when it was brand new. It's a 2004 Chevy Impala. The service is exceptional, Mr Luzzi is very nice and I am very pleased. I will be back for future service without a doubt.

Came here because I had a flat tire. But not only that I needed an oil change so this individual camilo took care of me really fast. Not only was he fast he had the best customer service I have seen in a while. I highly recommend checking this place out. Great job u guys. Ask for camilo hes the best! Jonathan Cook

Denis was more than fair, he gave me an incredible deal. I had the same problem a year earlier and was charged around $300, but Denis gave me parts and labor for only $130. Will definitely be returning! -Carissa

Best customer service and auto service ever! I've gone to multiple auto shops from Santa Barbara to Riverside and I had yet to receive the customer service I got here and auto service. The guys are so knowledgeable. It's been a relief to not have to keep receiving false diagnosis on my car. Rick's customer service is impeccable ??. Thanks guys! Sunkissed Honey
