El Cajon & Helix Auto Repair

Honest, thorough, affordable, knowledgeable, and just down-right nice people... everything you want in a mechanic.

Can not thank these men enough. We needed a repair done to our battery terminal at the last minute. They walked over to where my car was parked and then helped me get it to the shop since it needed a little more work. Very kind group of guys working here! Very inexpensive!! Thank you a hundred times! Comment from Greg K. of Greg's Automotive Business Owner 12/12/2019My gosh! I am tardy thanking you for your kind words. Happy holidays from Greg and the guys. If you are a service person or live with one, thank you for your sacrifice to our country and us. Greg Read more

I've been brining my '94 Jeep Grand Cherokee here for the last 5 years based on a recommendation from my Grandpa. When they first saw her, I was ready to drive her out to the desert and off a cliff. I had been going to another mechanic since I got her in 2000 - was pretty content and the Jeep was well maintained until it seemed like she was in the shop every month following a service for one thing or another (long irrelevant sorry but the last straw was a loose wheel that wasn't tightened after a rotation. I nearly lost the wheel during the drive home). I tried another shop based off of a couple recommendations. After some new mechanical issues cropped up (sputtering for power at high speeds, leaks every which way, would randomly overheat with "no known cause") and apparently couldn't be fixed, I ended up at Greg's. It took a week and some dough, but they determined the cause of the sputtering (original wiring harness was toast; they couldn't rebuild it or buy new so they sourced a salvaged part and rebuilt it), addressed the leaks (many but fortunately minor), replaced incorrect spark plugs the other shop put in, checked the other times the shop replaced, and did a thorough safety and inspection. My girl had been reborn! Today at 225,000, she's still running strong with services every 3,000 miles...and hasn't overheated since! I appreciate Sheri knows that money isn't growing on trees but that I want to keep the Jeep running. They do their best to rebuild parts or source rebuilt parts with warranties if new isn't available. I also appreciate that its usually the same mechanic working on the Jeep and that the they notate things that aren't 100% but maybe aren't top priority or necessary to safety and function but maybe comfort (ie suspension - what a difference new shocks make!) If the Jeep gets a good report after an oil change, I'll tackle an item on their list. Cars are expensive. Maintaining a car is expensive. Maintaining and old car is even more expensive, especially a daily driver. But I am thankful Greg's is around because otherwise the Jeep would've met her end in the desert or a salvage yard and that would be a sad end for an awesome car.

I have been going to Greg's for years. They are fantastic. I trust them implicitly and confidently refer friends to them. Not only do they do a terrific job on my car, they (Sherry especially) make you feel welcome. Bette Pegas Comment from Greg K. of Greg's Automotive Helix Business Owner 12/12/2019Another late response from me. I am sorry, Bette. We are always so glad to see you, and even glad to see Art. :-) You are both so warm and friendly. Your trust in us is very much appreciated. Greg and Sheri Read more

Nothing short of exceptional. After moving here roughly a year ago, I was incredibly nervous about finding an honest mechanic and through some recommendations, my fiance and I gave Greg's a shot. They don't try to sell you stuff you don't need, the prices are very reasonable, and the customer service is great! Mark is always a pleasure to talk to on the phone or in person and you can see they are very passionate about what they do. My Fiance and I always check with her dad who is also a mechanic back home just to make sure we are getting a fair price and Greg's is definitely giving very honest pricing and diagnoses. If you're looking for an honest shop with great customer service and repair times, this shop is absolutely worth giving a shot!!

Been going here for years. Excellent service and they stand behind their repairs. If you want it done right go here Been going to Greg's for over 10 years and I always get what i paid for. They use OEM parts so you always know what you are getting. There are cheaper parts out there but this way the repair shop and the customer always knows what you are getting. Excellent Service!

Such warm and friendly staff! The owner, Sheri, is very helpful, kind, and knowledgeable. She had a very caring and accommodating demeanor, which really eased my stress when I went in unexpectedly after my car stalled on me on the road due to a failing transmission. I've been to other mechanics in the past, but have never felt as taken care of as I did here. After offering a full diagnostic, Sheri advised me on what to do about my car's dilemma to a great extent, which is exactly what made me feel really comfortable with their business. If you are looking for a trustworthy mechanic that has your best interest in mind, this is a great place to go to.

Great service, great service advisors!

This is the best repair shop in San Diego County

We've had a Toyota Camry serviced there twice - the staff is very friendly and the work seems top notch.
