Awesome just doesn't feel like it's enough to say about having my car worked on by the guys at Juju!! Not only was my car well serviced but the exceptional quality work on my car was outstanding!! I don't know where else a person can take their vehicles and be given nothing but respect honestly and comfort of knowing our vehicles will be worked on by only the best mechanics who really know what they're doing without thinking this is a person that can be taken for a ride. Not here at Juju these guys only want a customer satisfied 100% and that's what they strive. Thank you George & Louie read more

Man this place is honestly terrible. I don't even know how they still in business. The service was slow as hell and nobody seemed like they knew what they was doing. I had to repeat myself like 3 times and still got the wrong thing. Like how hard is it to just listen?? And the workers? Super unprofessional. Standing around talking, laughing, acting like customers don't even matter. One dude was on his phone the whole time like he ain't even care. Felt like I was bothering them just for being there. Honestly just a waste of time and money. I ain't coming back and I wouldn't tell nobody else to go either. Get it together fr. read more

Best spot in the IE hands down, if you need anything done George and the guys are the ones to go to, quick and professional!

Great and reliable place to get service done. Most definitely recommend. Great customer service as well.

5 stars! I highly recommend to anyone in the IE looking to get their vehicles worked on. George and Louie have great customer service and their work speaks for themselves! We definitely be getting all my services done at Juju for now on! read more

Honda dealership in Loma Linda, ca. smh George is the goat by far highly recommend his shop to anyone with a Honda or Acura type R or si. And more.. read more

So I've been dealing with George and Louie for over 7 years with ALL of my car needs my bmw the Mercedez my Acura I had them fully build as well from ground up I have all of my family and cousins and even friends come here and every single person I sent has never been disappointed with the work they get done here as well as the pricing here is unmatched to anywhere else , the quality they give is a 10/10 from the work they do to the customer service they don't scam you here for your money they will even show you the price of cost they pay for your part and what they charge as well for doing it a lot of shops won't and a lot of shops buy parts supposedly they say you need but at times use old parts or just do it to charge you more then next thing you know a week or month later something else is wrong , well here no they don't sugar coat anything as well and tell you exactly what's wrong what needs to be fixed first how much time you have left before let's just say they told you another part will fail soon they'll be like well you gotta month or 6 months before replacing it Becuase they know it's expensive at times to come out of pocket for car maintenance so they work with you and make sure your able to get around regardless of the fact ! Again I promise you anything you need they can definitely get it done !!! No excuses and cheaper then what a DEALER OR YOUR DEALER will charge you and they have great choices for oil here themselves I always use Torco on my cars as well as my girls F Sport !

Top notch mechanic work with extraordinary skills and great people. I had my 93 Acura serviced here twice for some leaky fluid seals and suspension parts installation. The price that was quoted was considerably less than another specialty JDM shop. George and Louie took care of my car as if it was their own. They take great pride in explaining everything so there are no issues. I was able to meet the extended family and enjoy some good food with some deep conversations about how life can be sometimes. I highly recommend giving JuJu engineering a call for any type of car related issues. Although they have built some monstrous race vehicles, they are still able to take care of all customers with respect and honesty. I know I will be coming back for anything auto related in the future. read more

Georgi is a world class mechanic that gives you all the information you need upfront with no frills. His customer service matches the level of work he does. Car got a new motor mount, fuel filter replaced, drive belts changed and an oil change done in a few hours time. Car is driving better than ever, thank you. read more

always a great experience to stop by and get a service done by George. a super businessman who makes the experience top notch. an extremely clean shop/work area, spacious waiting area, and comfortable! appointments can be made, but for walk-in's? i've been more than lucky each and every time i have stopped by. thank you George! read more

Had a great experience here. George is very personable and honest with his communication. He made sure I understood what is going on with my car and explained everything so thoroughly. He is definitely knowledgable and is extremely gifted in what he does. I took my '16 toyota corolla here after having an oil leak and George fixed the issue. He even checked all other functions of my car and taught me ways I can better understand the longevity of different parts such as tires! Great service!! read more

It was late one evening when I was running errands and picking up dinner for my parents nearby, when I heard the strangest sound from my car. It was like a grumble... Ahhhhh!! Was it the engine? What's wronggggg?!?! Well when I parked, I was awkwardly crawling in front of my car and I saw that my under carriage was dragging. I opened my trusty Yelp app for an Auto shop and focused the map on the nearby radius since I didn't want to drive too far and drag my under carriage to the point of unfixable damage. Then I narrowed the search down even further for "open now" businesses. Most of the auto shops that appeared indicated that they closing in 5 minutes... all except JUJU BUILT ENGINEERED PERFORMANCE!! Yayyyyyy!! But wait... It looks like they do some fancy stuff, like the turbo engines and other fancy upgrades... I thought it was wise to call them first to see if they would handle a simple *under carriage* dilemma. George picked up and asked what type of car I drove -- Honda Civic -- and he instantly knew it was a plastic under carriage. So he told me to swing by for them to access the situation. George explained how they can reattach my under carriage if it was in good shape or completely remove it if it was too damaged. I really like how George laid out the possible scenarios based on what I described. When I got there George and Llyod were super nice. Llyod welcomed me into the shop to avoid the cold to wait while the were wrapping things up with their previous customer. Then they took my cute little Civic in and explained to me how under carriages could drag when you take your car in for maintenance and a clip isn't reattached correctly or if you ran over something. I'm not sure what happened with my under carriage. After quickly lifting my cute little Civic, Llyod slid under and swiftly reattached my under carriage. Yayyyyy!! And they wouldn't even charge me!! How sweet!! George and Llyod really saved me and I am eternally grateful!! This is a super nice and honest auto shop. In addition to the fancy engine work, they also do your simple maintenance like oil changes. I completely trust them with my car and would definitely come back for routine maintenance services in the future. read more

Brought my 2016 Subaru WRX (FA20) in for a catted J-Pipe (Downpipe) install after my catalytic converter failed on my aftermarket J-pipe (Downpipe). George was extremely knowledgeable, professional, and completed the service in a very timely manner. The prices are extremely cost-friendly, and George keeps you informed throughout the entire process. George also pointed out a few areas of concern to keep an eye on for future maintenance. After the install, George remained available to address some concerns I had while driving the car, and gave a very detailed step-by-step process to address these concerns within the same day (battery-related due to the car sitting for a while before the service). 10/10 service and just an all-around cool guy. Pleasure to work with and I will be keeping George and Juju Built on the top of my list to address any future maintenance needs for my subi. Thank you for the great service and expertise! read more

Excellent customer service, I was in an out in and out fast on my oil change. I used to go to the dealership but they use cheap oil unlike juju built!!! Also I have a really bad schedule because of work and they're open till late. But mainly they want your business and they have not forgot about customer service like back in the day when the customer was right. Talk to George he's a cool guy. read more

George is EXTREMELY kind and diligent. He spent a good amount of time helping me find options for a replacement engine for Kia Soul 2016 ! trim. I got a number of options for pricing, how to find a replacement engine and a clue as to why my vehicle is acting up (I called four other motor mechanics before Juju, and none of them offered the same amount of info as George!). I needed a "ghost" diagnosis before spending thousands of dollars on this car, and I got it. You know you've found a fantastic mechanic when you tell them WHAT happened without taking the car in and they can give you an idea of the root cause. That's important for a worrier like me. It's also important for the wallet! I am grateful to this business for easing some stress. Based on my potential quote, his labor prices are reasonable and he's 100% interested in customer satisfaction. Even if you're not looking to get immediate motor repairs done ASAP, Juju is the company to contact first. George WILL give it to you thoroughly and friendly, and you will not be dissatisfied with customer service here. I hope to work with Juju again in the future. - Alexandra read more

Super cool guys but.. went about a year ago to get my overheating problem fixed, paid a little over $500, a few days later my car was still overheating, went back again but the problem still kept happening... by this point I was over it I decided to just go to my dealership I was just trying to save some money in the first place so that is why i didn't go to the dealer in the 1st place. My dealership told me that my car was not fixed right.... It had the wrong antifreeze in the system and it had the wrong thermometer, the one installed was not meant for my car. Esp. the wrong antifreeze was a big concern... The dealership ended up re-fixing everything that was done previously only paid about 230$ for everything. My car has been running like new after the dealer fixed it. I wouldn't go back to these guys just because of my bad experience & the money wasted, but I know they have done a great job on other cars so just double check on everything if you have any doubts. read more

They were super fast had great customer service and George helped me fix my light! Highly recommend this place.

Had a few aftermarket parts installed on my Bmw. Staff is laidback and straight forward. Will be using them for all my future car work.

This place was an easy pick for my bmw m4. The guys George and Louie welcomed me and my brother with a ton of knowledge on our platforms (brother drives an e46 m3) They were cool and treated us like family immediately. Super fair prices, honest work ethic, and solid communication. Wouldn't take it anywhere else in the local area. Big shout out to these guys killin it. Cheers! read more
