    Theo is a great guy with integrity. Always had a great experience! I highly recommend Smog Dynamics to anyone looking for a fast, affordable smog from an honest locally owned business.

He was supposed to drive there on Saturday and get to So. Cal before dark. However, he left after dark. He passed Los Banos (Route 33 exit) close to midnight and his engine started running really rough and it was losing power. He limped to the next exit, at less than 25 mph, turn around, and come back to Los Banos. We picked him up around 1:30 and got back home at 3AM. At 8AM (Easter morning), we started calling mechanics in Los Banos. Of course, we used Yelp and sorted by ratings. We went down the list and left messages for everyone. We just prayed that someone would be willing to work on a holiday. Jesse was the only one who answered the phone. We explained our predicament. He agreed to help if we could get there by 10. He had a family picnic planned. My son's car was parked about 2 miles from Jesse's shop. We were able to get it running and over to the shop before 10AM. Jesse found the problem, was able to obtain the necessary parts, and had the car fixed in about 3 hours. He charged a very reasonable amount. My son made it to So. Cal before dark (a day late), and Jesse still got to spend the rest of the day with his family. If anyone I know ever needs a good mechanic in the Los Banos area, I would highly recommend Jesse and Advanced Service & Repair. Thank you, Jesse. God bless you.

    Eran is the best! If you're not car leaning or knowledgeable, and/or you're hesitant and doubtful…read moreabout moving forward on any used car, you don't have to worry about it and can completely trust SafeBuy and Eran! He's the consummate professional, excellent work ethic, and absolutely knowledgeable and competent. Eran is so awesome and accommodating. He seems ready and eager to work for & with you, and he made himself available as best he could with me. Even though it's clear from his website the area range he covers, and that he's open to go even further (for, in my opinion a small additional charge), he went extra far for me; and furthermore he's always ready seemingly at a moments notice (which won't always be the case, of course, but shows that as long as he's available, he'll jump to work with you [reflective of how awesome service & work ethic he has])! The extra (again, for an small [IMO] additional charge) he was wonderful in considering for me was even as far as a used car dealership in Roseville! Just FYI, for him Gilroy is too far (haha, had to try, because he's awesome and I was desperate for the car, so for him to). And he works hard to make it that his customers don't have to do anything additional, and that he'll take care of it all -- he doesn't expect you to meet him there (although you have the option; he offered/was-open for me to be there to do it with him, but since the dealerships were like 40+ miles out, I opted not to), or to meet with him beforehand, or even afterward; you can correspond and coordinate just text and/or phone. If anything, you just might have to call the dealership and give them a heads up (telling them the time and Eran's name & business). He goes out, takes the car for about an hour, and checks everything. But beyond that (and what I mean about excellent work ethic and consummate professional) is that he documents it all (photos on top of his notes), and he goes in, around, and even under the car and looks at all the nook and cranny of all the car parts & aspects. He took plenty of photos of anything remarkable of the car (dents, paint deterioration, oil/grease stains [underhood of the car], interior issues, etc.). He has a whole form with a checklist that checks ranging from fluids to condition of belts to lights working to hoses to condition of the tires & brakes and the rest; even takes note if there's a spare tire & wheel jack. Of course he hooks up his OBD tool to check for any codes. Then he sends you the report with all of his findings, gives you a call to talk it all over and he gives his impression, then you send payment -- he's really cool about payment and states "however you want to pay"; Paypal, Venmo, Zelle, Apple Pay, Cash, Check, whatever. He gave me the impression that I wanted him to be my own mechanic; so I even asked him. And it's a credit to him to have replied that, to keep professionalism and can't claim exploitation, he doesn't do both (PPI and mechanic). He is on the high end of what you might estim8 ($180; more if you send him outside his normal area/range [I don't believe more than $200]), but I was happy to spend that on him. I'm a novice with cars (general knowledge enough, but not enough to be able to identify whether car parts are in good order and/or would last or not), so I wasn't confident in my ability to buy my first used car. I used him twice (would have been three times, but Gilroy was too far away). In the end, the used car I got has worked great for the last 6 months. And he saved me from buying an amazing car (high end Hyundai; $3k) but in such under-the-hood horrible shape that it would've been 3x the cost of the price just to repair everything -- which is proven when I saw the listing remain for 2 whole months and priced reduced twice down to I believe $2800! After it all, I brought my used car to 2 mechanics after him, and they confirmed 4 out of the 6 concerns he had -- which, granted, it's not like Eran has a car lift and a whole lot of time to thoroughly check as much as a mechanic with a garage would. He mistook cosmetic blemishes on the serpentine belt and the brakes as old age and maybe needing to be replaced -- which didn't end up being the case. But he did get the transmission deficiencies, signs on a certain valve gasket, parking brake, and other aspects right on the mark. I can't say good enough things about him! I was only able to feel confident enough to buy the really old used car that was in my budget because of him. And it's been nothing but a success! 6 months later, after taking care of the issues and potential concerns Eran noted, the car has not given any problems (that could have been foreseen; it still is a really old car so some things are bound to have come up organically) -- proving how much Eran and SafeBuy is really stellar and impeccable! If you're not the best with cars, you can absolutely trust Eran and SafeBuy; as much as you can trust his willingness, commitment, integrity, experience.

    Had a great experience. The owner responded within a few minutes of my inquiry, and was able to…read morecome out and meet me to perform the PPI later that day, and went over the results with me.

I previously went to another auto repair who listed several issues (engine oil, brake belt, leaking water coolant, replace filters, tires, etc). I definitely needed serious repairs done. The previous shop quoted me $3k including labor. I asked around and was recommended Lou's. I called 730am and he called me back 15 mins later and welcomed me to bring the car by for a free inspection. He said the previous shop was correct in their assessment. I did need all those repairs but a couple could wait until my next oil change or in 5000 miles. He also said I could go to Costco to get my tires done (a place that referred business elsewhere def means he's looking out for customers!!). He quoted me $1696 including labor!!! I was shocked and grateful for his honest quote. I was able to leave the car and pick it up at the end of the day. They also test drove it on the streets and freeway to make sure everything was solid. I cannot rave enough about Lou's. I trust him and his crew 1000%. He made a life customer.

When I was trying to pre arrange to bring in my car to get checked on he wanted to have it there on his time and not mine. Once I agreed to his time and date he acted like he gave into what I needed he asked why I showed up that day and claimed he agreed to Monday. But I'm a very meticulous person I had Friday on my calendar he even made a comment for me to uber to work bc I said It would be an issue to bring on a work day and a non issue on my free day. When he finally got the part for my car he waited until I showed up to tell me the part didn't work out. So he left it in when I asked why he didn't simply communicate with me and put my old part back in he said it was too much or double the work. Then later proceeds to call me to say he needs the car back to take out the part and put my old part back because he needed to return the part. Very strange bc he could've saved both of us some time just doing it then and there. When I asked for my money back he said he was going to deduct 100$ for the "work" but I don't think it's just taking in consideration that my car was not fixed. He ordered another part and claimed it arrived broken so I'll just take it to Honda and pay whatever their fee is to get it done correctly. He also refused to give me any invoices / itemized receipt for the parts / work being done. Saying it would've been more to write it up in the shop meaning I don't know if I'm being charged accordingly or overcharged.
