Tesla model y front bumper repair
Helen M.

Everyone at Diamond Collision did a fantastic job with repairing my front bumper. I called around to so many other places and was given outrageous quotes for price and the time it was going to take to fix (one place wanted to hold onto my car for 2+ weeks). DC got it done in 4 days. Was able to go out of town, come back and reach out to them to pick my car up early too. Super responsive in communication and answered all my questions. Great work on the car. 10/10 recommend this place.

Perfect color match and detail. Looks brand new

Diamond Collision went above and beyond from helping me deal with my uncooperative insurance to the great body work. They made sure to communicate with me through the whole process, which I appreciate. I highly recommend calling them for any body work you need done. Great quality for a great price!

I had my 1964 impala painted here. I chose this shop from others because they are a family owned business and second because the price was right. Giovanni and his parents are the owners. It was a pleasure to do business with them. My car came out great. Not only they did a great job on the prep and primer and paint. They did a great job of putting everything back together. Bumpers, grills, trimmings , weather stripping, door handles , emblems etc...I have no complaints and will use them again. So if you need a paint job on any car especially classic cars. Give them a call . They are great people and great at what they do. Appreciate all the hard work Giovanni and crew. Thanks.

Gio, the shop owner, was very welcoming and quick to answer my inquiry. My car had gotten vandalized and he was able to take my car in the day of and got her fixed up within the next day for pick up. What I really love is that he was able to have my car nicely washed in and out. Always making your car look brand new after a quick fix up. 10/10 service. Thank you!

After
Cassandra T.

Diamond Collision really helped me out after my car accident. I regretfully trusted the tow truck driver originally and allowed them to tow my car to another place (Global Collision in Garden Grove) and my experience with Diamond Collision was exactly as it should be. First let me preface by saying, Global Collision are a pack of rabid wolves, preying on anybody and everybody. They kept my car for 18 days, charging their ridiculous storage fees and charging me $350 for a quote I NEVER received. The at-fault-party's adjuster was trying to obtain the quote and for whatever reason they wouldn't supply one. Then when I wanted to have my car picked up and towed to Diamond Collision, they told me I had to pay the fees, which were $1800, IN CASH or they wouldn't release my car. Every single person who works in this trade was shocked they held my car hostage and demanded CASH PAYMENT. Now, with Diamond Collision, my experience was the complete opposite from Day 1. The day they got my car, they provided myself and the insurance adjuster with a quote in 2 HOURS. So why Global Collision couldn't get us a quote in 18 Days still baffles me. At Diamond Collision, you will be taken care of and your car will come out looking better than before. Here are photos of their work.

Giovanni and Diamond Collision did a great job. I got 3 quotes and they were the cheapest by a few hundred dollars. They gave me an honest assessment of the work and the options. Once scheduled they completed the work on time and kept me informed all the way. Highly recommended.

Dent

Giovanni gave me a great and very fair priced quote. He made me feel respected and safe. I needed a dent fixed and it ended up great. I didnt have to order a new part either.

Mach 5 Insurance Services

(24 reviews)

Wow! I cannot say enough fantastic things about Mach 5 Insurance Services! From the moment I first…read moreconnected with them, it was clear this wasn't just another insurance company; it was an experience defined by professionalism, incredible knowledge, and truly outstanding customer care. For years, I stuck with another broker in the Westminster area, primarily because it was a default recommendation from a real estate agent. That experience, frankly, was a nightmare. Our previous broker was unresponsive, and when our insurance company tried to block us from renewing our coverage, citing an "unlivable" roof (despite us having repaired it years ago and providing proof), that broker was the absolute worst to deal with. They wouldn't respond until our coverage had already lapsed and we had to scramble to find new insurance. To add insult to injury, they then tried to charge us for a renewed coverage we never agreed to! All that to say, when we finally made the switch to Mach 5 Insurance Services, it was a NIGHT AND DAY difference! Emails and phone calls are responded to incredibly FAST, which is a breath of fresh air. We worked primarily with Shannon, who is the office manager and hands down the most professional and competent insurance agent we have ever had the pleasure of working with. We love Mach 5 so much that we decided to switch the policies for both of our homes over to them, specifically requesting a change of agent so that everything would be handled by one office and with their team of honest and responsible agents. Even when it came time for our annual renewal, Mach 5 worked diligently with us to ensure we were getting the best bang for our buck. If you get the chance, I would recommend anyone and everyone to go with Mach 5 Insurance Services! They are truly exceptional!

Just got my homeowners insurance set up through Mach5, and the whole process was seamless. Shannon…read morewas amazing -- super helpful, patient, and honestly just a joy to talk to over the phone. She made everything feel easy and took the time to walk me through the details. Highly recommend working with her if you get the chance!

Farmers Insurance - Tim Weidenkeller

Farmers Insurance - Tim Weidenkeller

(5 reviews)

I've been a long-time customer with Farmers Insurance, but my experience with Tim Weidenkeller's…read moreoffice on Los Alamitos Blvd has been extremely disappointing. Farmers decided to CANCEL all landlord/rental insurance policies in California. Tim's office offered me a quote through Foremost Insurance (their "commercial landlord" division). The quote and bill they sent were over three times higher than my previous Farmers policy. The "Foremost" bill stated I could pay online or by check if I wanted to proceed (see image below). I did not agree to this policy, and I found coverage elsewhere. Despite NEVER authorizing Foremost or Farmers to enroll me in this new policy or to withdraw funds, Foremost took the ENTIRE PREMIUM amount directly from my business bank account. This means Farmers GAVE MY PRIVATE BANKING information to Foremost WITHOUT MY CONSENT. It has now been 20 days and I still have not received a refund! This is a serious lapse in ethics, a breach of trust, an unauthorized withdrawal, electronic funds transfer fraud, breach of contract and violation of privacy laws. Today is August 15, 2025, and the last time I received an update was on August 4, 2025, where Tim Weidenkeller said he would follow up with Foremost and get back to me. Well, I'm still waiting on the follow up and more importantly WHERE IS MY REFUND FOR MONEY THAT WAS STOLEN FROM MY BUSINESS ACCOUNT?

We had homeowners insurance with Farmers for 32 years, and our policy was recently cancelled…read morewithout any explanation whatsoever. There were no changes to the property, no major remodels or upgrades, nothing that would have/should have had any material effect on our insurance. We're right in the heart of the city, surrounded by concrete and steel, not some densely wooded area or anything of the like. Reached out multiple times to Tim by phone and email, got nothing but silence - a complete 'ghosting.' I'm utterly shocked at the lack of professionalism and complete fecklessness that we cannot get an explanation after 32 years. Run away from Farmers.
