This place does RV Smog Checks. $100 is standard charge for RV Smog Check - but call to get exact quote.

Not very many shops are open on Sundays, but I stumbled upon Keep It Runnin Smog when I thought I had a nail in my tire. I did a Yelp search and found this place. I drove to the location and there were two gentlemen there to help. I think they might have been a father-son duo. The older gentleman helped me right away and informed me that my tire was just lacking air. He pumped it up and didn't even charge me. Another guy arrived and he brought coffee for the two other guys, which I thought was a nice gesture. Who wants to work on a Sunday? Anyhow, I asked again if they were sure I didn&apos

I went for a Smog check. I had issue with some reading. He asked me to come back after a long drive. I did so. But when I came back he basically said I did not do it, when in reality I did that, then he asked me to do that again and threatened of charging the full amount the next time. I never went back as I was clueless how to fix this. Went to another place who clearly instructed me to drive me within around 65 mph while not turning the AC on and if I could not do he could do it for extra charge. Fortunately, I followed and it worked.

I went in for my smog check and the service was fast and there was no waiting. I found them them to be very friendly and I am handicapped and they were most accommodating to my needs. I would highly recommend them for smog checks and plan on returning in the future.

I needed a last minute smog check to renew my registration soon. Called them up to see if they take walk ins. They told me to come on over and had everything going right when I pulled in. Fast and easy

Well the business owner is pretty bad. Charged me $50 for running a smog check without giving me a proper invoice while the actual price should be $31.75. Learned a lesson to never use any suspicious service like this... Tips for anybody who has to do business with them. Make sure to double check their service price before letting them start the work. Do not let them scam you with fake price...

Service: Transmission fluid replacement. Friendly, worked me in on very short notice, fixed the problem quickly, and at a better price than everyone else. Vu also pointed out a problem that a different oil change place left for me.

This place is only good at smog check. Do not rely on them for auto repair. they gave very unprofessional advice and wrong diagnosis.

I've finally found an auto-mechanic I trust.

Took my Ford Mustang to the Ford Service-place on Steven's Creek, San Jose two years ago. Carefully explained that it kept running out of coolant, and the AC wasn't working, AND that I had had it looked at by an auto-mechanic in Redwood City two months earlier, and they had told me nothing was wrong, when clearly there was. Ford charged me $700 dollars, told me everything's fine, just refill freons.

Same problems persisted, so we've been driving around refilling coolant every time we fill up gas, and have had no AC - for

Great services and good prices. My parents have been coming here for a while and now I do too. From oil changes to smog to just replacing the bulbs in my headlights.
Not going anywhere else for my car needs.

Super friendly and efficient service here for Smog Check. Greta pricing too. My old go to smog shop closed so I definitely found a great place to take my vehicles for smog.

The service we received here was friendly enough, but I received inaccurate information and basically wasted my money here. Our AC stopped working after 10+ years of working fine. I asked several times if there could be a leak, but I was told no, it just needs to be recharged with refrigerant. They drained and recharged the AC with cans, the AC started working again, and we were on our way. It worked for a few weeks but the AC is weakening again now just like before, so there must be a leak.

I appreciate their effort to help me out quickly, but I feel that they misled me with inaccurate advice
