Top Line Performance

My co worker recommended this shop for my Highlander that was shimmying when it reached higher speeds. They diagnosed it, and repaired it in TWO DAYS! I don't know any dealer that can work as fast! I drove the car up to Big Bear that weekend and could not believe the improvement! I will not be taking that car to a dealer ever again! Thanks Mario and your team!

Car had check engine light come one. They were able to confirm the diagnosis to the EGR valve getting clogged up. Professional and up front on the repairs, and very easy to work with.

Please give them your business ,. Outstanding experience with them, they installed a performance pack for my 5.0 Mustang . Best price in town quick turn around and quality work. Will return in the future.

Top Line Performance lifted my Mercedes Benz Sprinter in June. First time customer and very happy with the experience. From the moment I contacted Josh about the job everything went well. Josh made an effort to schedule me in quickly, I received and estimate that was LESS than the actual cost; the work was done perfectly and on-time. I would strongly recommend this shop to anyone.

Had complete tune up (plugs/wires/dizzy/valve cover gasket/etc.) and brake booster/master cylinder done on my 94 Land Cruiser. I drove about an hour and dropped it off for a couple days...a lot of work! Everything was top notch...no complaints after 3ish months of the work being done. Hard to find competent Land Cruiser specialist shop...will be back.

These guys do great work...simple

This shop is AWESOME. Great experience starting with the first phone call inquiring if they could look at my car. The work they did was completed in a timely manner and a more than fair price. This shop is all about return customers.
Thank you

Mario and his crew are great. I was having issues with my 85 FJ60 and I took it to TopLine. Mario went above and beyond for me and made sure I got back on the road stronger than ever. Wont trust anyone else with my FJ.

Always fair & honest. Never pushes extra service. Uses OEM parts. I have recommended Mario & Jr. to all my friends with mechanical issues. They were never disappointed with Topline Performance, nor am I. Thanks Mario for always being there to help when I am in a pinch.

Topline is the only place I will take my FZJ80. Their customer service is incredible and they do top notch work! The owner even gave me his cell phone number and told me to call him any time if I had any problems while I was driving my 25 year old land cruiser half way across the country.

Had our 2004 VW Passat repaired..We are completely satisfied and will use them whenever our vehicles needs their services.

Thank You Mario, JR, Kevin, Agustin, and Mike...You all treated us very well and we appreciated.
Our car run beautifully, Its my fault that I kept driving the car while the warning light was on. Could have been less damage if I had.
it was worth doing the repair on a fairly new car with only 60,000 miles. Better than having car payments.

Best wishes

They are honest and do what it takes to satisfy the customer. I always feel confident after they have repaired my car.

Can I give 6 stars? My headlights got broken so I stopped by and a gentleman called Josh helped me real quick! Highly recommended if you are in OC!

Mario and his crew are about the best mechanics metal fabricators every custom car or car. Is in to be worked on he's done correctly and right I guess you could say that Mario is a perfectionist he's a master of knowledge of automotive

Brought my car in to repair my breaks on my 5 series after it has been screeching for a while. The staff at top line did an amazing job in fixing my brakes in no time at a very good rate. Thanks!!

This place goes above and beyond. The owner even went out of his way to fix something he thought might cause me a problem. Under my hood the clip that keeps hood up was broken. They run a top notch business .
