    I am a dealer and i know dan for few years already. Dan is got the best prices despite whatever the guy said in the previous review. Dan is always honest and professional. For all the cheap people out there, no one puts a gun to your heads and force you to buy the product or services, so if you don't like the price just don't buy it, Don't put bad reviews for businesses for no freaking reason.

    My Silverado pick-up had backfired and the pressure broke the flange on my driver side header. Through word of mouth I was able to find D. Fiero Muffler and take ot there. They were able to weld the flange back on and charged me a really good price. I was happy with there service and would recommend them to anyone else.

    See all

    I am disappointed with this shop. I went after seeing good reviews.Although, I like the customer…read moreservice from owner and the technician. I went in for transmission fluid change earlier in February in my Toyota Camry 2018. I bought OEM Toyota transmission fluid and asked Joe to help do drain and fill.The drain and fill was completed. After that there was a rough driving issues started. I went back to show my car to joe and he drove the car he told me he don't see any issues. I wanted him to check transmission fluid port on if there is low transmission fluid he didn't agree and told me I might be overthinking. I went to different mechanic in April and he checked. I paid $100 to reopen the port for transmission fluid and what we saw was no fluid came out from the primary port. He added 0.5 quarters left. The issues I have had for rough idle and need to have higher RPM on slope went away completely.According to him you have to keep the car running when you drain the fluid and you need to have it at the right temperature he said the drain and fill wasn't done correctly that's why there was still room for fluid. The viscosity of the fluid makes a difference in how much you can fill and drain. He double checked for leakage and there were no leaks either. When I went to joe and asked about don't you have to keep car warm to see if temperature is right? He said you only do it when there is a leak. I don't think Joe knew enough about mechanics of New car. I wasn't overthinking when I went to ask Joe for help and asked to recheck the transmission fluid. I paid $260 for labor only( $160 to Joe and $100 to another mechanic) for same job. It's really absurd. Overall this could have damaged my transmission. I think for future the customer advise should be taken seriously. I know my car well so I know when it's not acting good. I have been driving it from 10 years.

He is very transparent when it comes to the breakdown of pricing, and I have always felt that the quality of work he delivers outweighs whatever the price is. I've been here for regular maintenance, emergency issues and if I just need an honest opinion, he does it all! I have his number on speed dial! just kidding. This shop is honestly best in the valley! The best!

The problem is after paying $500 for a new starter, my van still wouldn't start. After hours of trial and error, the mechanic decided to clean my battery terminals. Once finished, the mechanic determined it was a dirty terminal/battery issue, and not the starter. I could have cleaned the battery terminals for free. I could have bought a new kit for the terminals for $20 on Amazon. Instead, I'm out $500 for a starter I didn't need. I tried looking for a solution with Francisco. I tried to be understanding as I am a business owner as well, and I know mistakes happen. However, Francisco only offered me my $55 inspection fee back. At first, I was insulted. I could have a asked for a complete refund. But then I thought to myself, I'll just take the $55 and be done with this problem. We are going on 4 days, I have been left on read multiple times, and am still waiting on the $55. I tried to be nice but instead feel taken advantage of. I know how costly these reviews are to businesses, I hope it was all worth your $55.

As a certified body shop, they're well-equipped to handle advanced Mercedes technology, such as parking sensors and collision warning systems. What's noteworthy is that they kept communication throughtout the process beyond my own Insurance company. In fact, once the damages were evaluated my insurance company was only allowing the body shop to repair versus replace a few a components. Can't thank the shop staff enough for not allowing my insurance to cut corners. They sent me documents from the manufacture showing the guideline on what is not repairable. With this information, the insurance company didn't take another second to revise the repair order to replace with new parts. I didn't expect such things ever to occur but then again insurance company is also a business who try's to minimize their overhead. For Mercedes owners in search of a reliable and certified body shop, I wholeheartedly recommend The Shop Collision Center. They truly have cusotmers best interest in mind.

    UPDATE in response to the owners reply!…read more When my vehicle was first diagnosed, I was presented with two options: replacing the cylinder head or replacing the engine. The cylinder head repair was described as the more economically reasonable option at the time, and I relied on that professional assessment in making my decision. The repair took over one month to complete, and the cylinder head was sent to an external machine shop. Although outsourced, the repair was coordinated, billed, and released under his shop's responsibility. I proceeded with this shop because I needed reliable transportation for work and was informed the repair would take approximately a month. The availability of a loaner vehicle allowed me to continue working during that extended repair period, which was a significant factor given the timeline. After the vehicle was returned to me, it broke down on the freeway. I was then informed that the cylinder head could not be reprocessed and that the only remaining option was to purchase a replacement engine. At that stage, I no longer had a functioning vehicle, so this was not an elective decision but the only viable remedy presented. Before purchasing the replacement engine, I consulted with (David the owner) regarding where to source it and whether I should proceed. I relied on his confirmation before moving forward. While labor was not charged for the engine installation, no warranty was provided on that work. Regardless of warranty terms, the obligation to disclose safety related defects prior to releasing a vehicle remains. In his comment, he states that engine mount replacement was recommended. I was not provided with any written estimate, documentation, or verbal recommendation to replace the engine mounts prior to installation or before the vehicle was released. The condition of the mounts was identified only after I obtained an independent inspection due to ongoing noise concerns. That inspection revealed multiple broken engine mounts and a severely worn transmission mount. If mount replacement had been clearly recommended before release, it would have been documented and addressed at that time. My concern has consistently been transparency, communication, and the release of a vehicle with undisclosed safety related defects. This response reflects my experience and the events as they occurred.

    Took my car here on Friday, spoke with David about a coolant leak. After a conversation an order…read morewas placed for a new radiator. Asked me to come back on Monday for the appointment. I've dropped off the car right when they open at 8am, and received a text saying that my vehicle was ready for pick up at 12pm. Over fast and efficient work. David even showed me the location of where the crack was on the old radiator. Overall very satisfied with the work. I tend to get anxious leaving my car with someone else to work on it due to how much work I put into getting the vehicle. But with David he made me feel like he also understands the value of what good work should be and how to do things the right way. I will be bringing my business back here for any future projects/issues.
