Diablo Offroad And Performance

Amazing shop! Hes helped me with everything from installing a drive shaft to rebuilding transfercases! Cliff really knows his stuff.

Another satisfied client. Thanks Cliff and Mike for making my day… replacing my broken leaf spring and for dealing with all the complications that went with it.
You can’t please all of the people all of the time but today you made this person happy! You guys are the best.

Cannot say enough good things about Cliff and Diablo Offroad. He is honest and does incredible work. He has taken care of my Mercedes since I bought it and I would not consider taking my car anywhere else. Always reasonably priced and I can count on the work being done correctly and in a timely manner.

Came in last minute an hour and a half before closing and Cliff happily took in my car and installed my catback exhaust quickly, properly, and affordably. Will take my car back here to install my header and will recommend all my friends to have their work done here!

I had a great experience and am beyond thrilled with the results. Cliff runs one of the last honest shops in the area hands down.
I got a lift kit installed as well as a couple freeze plugs and a o2 sensor for which pricing was extremely fair. I’ll definitely be using this shop for all my upgrades and major maintenance in the future.
Thanks a million,
Joe

I was very disappointed with my experience at Diablo Offroad and Performance. I found out about Cliff on Unilocal and saw the great reviews so I thought I’d give him a try. I originally went in needing four new brake pads and rotors and he quoted me at $ 180 which was awesome. I also asked if he would do a quick inspection of the car and he also told me he would do an oil change at no extra charge.
I dropped my car off a couple days later for service and he told me it would take 2 hours or less. I called after I hadn’t heard from him for 3 hours and he told me they were just getting to it. Once I got there I had to wait another 45 minutes at the shop. When he told me the car was finished and I went to pay, he told me the total would be $ 420! I also asked if he did the oil change and he said he didn’t. After making me wait another 20 minutes he told me it would be cheaper to just go to JIffy Lube.
I would have really appreciated him letting me know the price would be a lot higher than he originally quoted. I then had to make a separate trip to get the oil changed.
And two weeks later my check engine light is on. Thanks for the inspection…

I paid Cliff to do a ring and pinion swap from a 3.73 gear ratio to 4.88 on both front and back of my Jeep Wrangler, as well as install a Detroit True-​Trac limited-​slip differential. Speedy and quality service, he’s a cool dude to talk to as well. His prices are better than other places for similar work. Thanks Cliff

I found Cliff on accident. I was having car troubles, I stopped because they were close. I had been to two mechanics in the months before who had told me the same thing: I needed to replace the seals on my engine, that my suspected oil leak was a real oil leak, and it would cost about $ 1000. I would also need a new Power Steering pump, and it is in a tricky location, so that was going to be expensive too. I just asked Cliff if I would be able to make it two weeks, or if I had to do it right away for safety reasons. The car was making really odd noises and I had become concerned about driving the car.
Cliff brought my car in, even though they were busy, offered me a ride to work (which I didn’t need, but that was really nice of them), and during my work day figured out the I did not have an oil leak, that I also didn’t need a pump. That the power steering fluid was leaking all over because the hoses were bad. They fixed that, made some other adjustments to make it run better. They gave me my car back when I was off work for under $ 400. They then had me come back so they could make sure there was no oil leak a week later. Sure enough, a month later my car is running BEAUTIFULLY, My gas mileage increased by 5 mpg, and they could have easily done the job the other mechanics had told me I needed and I would have believed him it was necessary. Instead, he saved me a bunch of money, showed me how to do one of the easy fixes myself because I was concerned about finances, and made my car run SO much better. I have a new mechanic for life.
These guys are the best. They are honest, and they know what they are talking about. I would recommend them to everyone.

Cliff is awesome! Not only did he diagnose a problem that I had two other places look at, but the first time he sent me back to the original person to try and save me money… The original place still couldn’t find the problem and spent my time and money fixing a non-​issue… I brought the vehicle back to Cliff, he gave me a very fair price, fixed my vehicle in one day even though a second issue came up… Most importantly he spoke to me in a language I could understand and was very nice and understanding! My car is driving like new, and hopefully I don’t need any repairs soon… but if I do, I will definately come back here!

Cliff is a generous person. The last honest mechanic in walnut creek. He is trying to keep your car on the road and not make a fast buck. I have an obscure rock crawler project that not many people take on. Cliff was the guy who would. HE LOVES ISUZU RODEOS!!!

Cliff and his guys are excellent.
They really know their cars and are VERY fair with pricing. Too fair Cliff!
I have had a couple of cars worked on including an old FJ40. His knowledge of this car was excellent.
Thanks guys.

I am surprised by all the good reviews. I took my Land Rover there today to be fixed for a check engine light. When Cliff (owner) dropped me at BART, he told me the diagnosis would be done, whatever parts needed installed by end of day. I had to call twice and at 4pm he said he was just getting to it and had a busy day. I asked what happened to the promise of having it done by the end of the day and he rudely told me «many people came in unexpected and with phone calls and he just couldn’t get to it». This is how you run a professional service repair shop and inconvenience your customers? I then received a call back finally at 4:30 that it was a loose clamp and it was fixed. After picking up the car, I had not even gone a mile and the check engine light comes back on. I immediately called him to see if I could bring it back over to be told «you will have to come back another day as I cannot do anything for you today». Not only that but I was charged over $ 400 for back brakes, oil change, and air filter. I might as well have taken it to the Land Rover dealer and let them gouge me on price and lousy service.

Unfortunately, I have a high mileage car. Fortunately, I found Cliff!
As a single woman, sometimes you wonder if you can trust these mechanics… I’m here to say YES if it’s Cliff!
Cliff is amazing, has helped both me and my daughter with our engine/​brakes/​clutch/​broken mirror/​timing belt and battery issues (not all at once… lol, gone over and above to make sure things are done right the FIRST time, is professional, explains clearly what is happening (even if sometimes I don’t totally quite get it) and has an old fashioned approach to customer service.
I could not recommend him more! Great service, knows his stuff, fair prices and professional!
Thanks Cliff… you have a customer for life!

Cliff is the most trustworthy mechanic out there! He will be completely honest with his evaluation of your car troubles and more than reasonable with his charges. He’s an extremely intelligent man, and I wouldn’t want anyone else to touch my car. He makes sure to try to obtain any parts you need at the lowest price possible as well. I feel that he treats my vehicle the same way he would treat his own. He’s a gem in the auto repair world.

This was actually my second experience with Diablo Offroad and Performance. The first time I went in, Cliff spent 20 minutes convincing me to give it a shot on my own based on my experience. He let me know if I had problems bring it in. Well I took his advice learned a new skill and felt pretty good about it. Smash cut to last week, with a new born at home my time to work on my own cars is greatly diminished, after retrofitting a bigger brake master cylinder onto my 4runner to handle a disk conversion I couldn’t get it 100% right. Brought it into Cliff (btw– when I got to his shop a customer was politing informing Cliff he should have charged him more given the work he did to his car. That’s right a customer telling a business owner he didn’t charge him enough) he explained what he thought was wrong, but still tried to convince me to fix it myself. After explaining the whole issue of no time, he agreed to work on it. In the end I got a bill that was more than reasonable and about a third of what have been worth to fix.
I’m super happy with the work that Diablo Offroad and Performance did.
Cliff is awesome, and takes time to explain what needs to be done or how he fixed the problem. Wish I could give him more than 5 stars

Outstanding service, very reasonable prices, and no other mechanic out there like Cliff. He is very personable and a whiz with virtually any kind of car out there! I brought my 1978 Alfa Romeo Spider in for a little help… and out she came running like a champ! I will no doubt be coming back to Diablo Offroad in the future!!!

I love having my car worked on here. I am able to bring my own parts in and I feel that I am treated like a person. Not just a dumb girl.

Cliff is the owner, he will tell you straight up what you need to get fixed, how much it cost, no BS here not up sell other crap like some the other shady auto shops, best price around town and i’ve been to a lot of places, coolest dude you’ll ever meet, this is the only shop i’ll go to.

Went there to talk shop with Cliff, found out he’s a bit more than just a mechanic. He has a good philosophy about cars (think «do it right the first time). Amazingly enough, he thinks green (is that possible with a mechanic?). Most of all, he seems to talk with you rather than at you. Nice. I recomend him highly.

This is a one-​man show. The owner is a second generation tech with years and years of experience. Clifford will take care of your needs. He is carrying on his family legacy by offering thorough, full-​service repairs at a fair price.
No, not a «Walnut Creek» fair price, a real honest-​to-​goodness fair price.
No job too big or too small. Just remember it is a one-​man operation. So be prepared to book an appointment, or leave your vehicle until he can access what needs to be done and make recommendations.
He literally brought my old jalopy back from the dead and appears to be doing that consistently while juggling quicker turnaround services.
My car runs better now than it should thanks to Cliff at Diablo Offroad And Performance!
