What HG Performance Customers Say

Jordan E.

Everyone here has been amazing. Had a bunch of work done on my S3 and I couldn’t be happier with the quality of work, communication and no surprises. I paid what I was quoted and was even reimbursed for my Uber rides to and from the shop. I’ll be back soon!

I dropped by with my wife’s car and my truck on zero notice a couple weeks back and Oscar and the team took me right in and addressed a couple issues I had going on right there on the spot. Oscar and his crew are amazing and I highly recommend them to everyone! Thanks guys!!!

Di L.

Extremely professional individuals. Really nice facility and really detail-oriented and the work and pricing that they are providing in their services. The service advisor even went to the extent of emailing me ahead of time a detailed list of all of the work being performed and the cost breakdown between parts and labor. Really great people to work with, knowledgeable on Porsches, honest in their advice on performance enhances and they are not pushy sales types.

This place is truly the best! I will always come here for my car needs. Omar and Bill really helped me a lot. I’m very impressed with their customer service and knowledge about cars! They did a smooth checkup on my car and gave me a great deal on the tires I wanted and set them up perfectly. Thank you so much for your help!

Kyle I.

HG Is the only place I trust with my car. I know they treat my little Porsche Cayman with the same care as they do with the Ferrari 458 or Mercedes 300SL parked next to it. Very professional, very knowledgeable team. Two thumbs up.

The team at HG was simply awesome. I needed to have a wheel balance issue addressed and they had me in and out within an hour, even though they were extremely busy. Thank you to Omar for taking great car of me and my car. I will recommend everyone to your shop in the future!

Clement C.

Omar and his team are just the best in the game. I am bringing my Ferrari 488, Porsche 991 Turbo S and Range Rover SVR over there. They are always doing modification or services on my Porsche and Range Rover. I recently changed my exhaust on my SVR for a Quicksilver. They have been more than professional and affordable!

What would I do without HG performance?! I recently moved to San Diego and in the last 7 months they have helped me tremendously. I used to only trust taking my car to the Mercedes dealership but this is the first place I’d take my car now. (Worth the 45 min drive for me) Huge thank you to the owner, Omar, for all your help! Will be back!

Chris W.

I have used HG performance several times and these guys are plain awesome. Excellent customer service! Omar and his team managed to get me the piece I was looking for (Exhaust Cut out + Wireless remote control) for the best price available!! As soon as the pieces arrived, they communicated with me on the order status and had the pieces delivered to me. Highly recommended for tune-up, customization, even simple check up or repairs, you cannot go wrong with them!

Porsche 911tt owners – I’ve had two fairly large projects performed by the techs at HG along with some regular service and I’ve only ever experienced professionalism, honesty, excellent communication and excellent workmanship.
