It was very easy and convenient. I requested a quote on Yelp and received a prompt reply, got in my car and went to have it completed and was out in 15 minutes. Smog and certificate all included in one price. read more

Came here for a smog, they are one of the few places that can smog cars that have been lowered! Highly recommend coming here

Called and they said to just come in. There was one person ahead of me and I was in and out within 20 min for $50 out the door.

I was looking for a smog shop on Saturday at 3:30pm and found MN Star Smog on Yelp. They had high reviews, so I gave them a call to see how long the wait was. I then brought my car in at around 4 o'clock and had one vehicle ahead of me. I was there for a total of 15 minutes and my car was done. It gave me enough time to make it to AAA by 4:30pm. 5 star service and 5 star customer service. I definitely will be using and highly recommend MN Star Smog. read more

Stopped by here to see if they had time for a smog test. Only had to wait 15 mins as he finished the car he was working on. Quick smog check. Comfy chair to sit in as I waited. Passed the smog and he gave me a copy and entered the info in the system for DMV. Nice conversation, the guy that helped me seems to be a very kind person. read more

I arrived to have my Highlander smogged today at Mn Star Smog. I left with a feeling of gratitude and calm. Robert not only helped me with my vehicle but our conversation afterwards left me with a grateful heart. He was exactly what I needed today. He is not only knowledgeable but an amazing man but one who genuinely cares about his community. He is a Vietnam vet and just an incredibly kind human being. I'll definitely be back. Oh, the prices, UNBEATABLE. read more

I read Melvin's review on Yelp and he definitely lives up to his reputation! He was very nice and had both our cars ready in less than half an hour. His prices are also very reasonable! read more

Melvin from MM Star Smog is a reliable choice for CA DMV Smog needs. Been with his original company, and where he continued the brand and branched out on his own. Been a customer for nearly 5-7 years. Straight forward and clear communications. Can't ask for anything more. read more

First time I've ever had to get a smog check and I'm glad I chose this place. The woman at the counter was really nice and the inside of the business is amazing. Basically brand new. Like the other review I too was offered a water and was told I can change the tv to whatever channel I like, there's not much of a selection for channels but that's no big deal, I'm here for a smog. I even used a coupon from Amazon Local, a great deal it was. I would highly recommend coming here again. For those who are confused, it's the old safelite auto glass repair shop. Right across from the Lexus dealer. read more

I came in during work between meetings and I was literally in and out within 10 minutes. They were friendly and welcoming. Waiting area was very clean unlike other auto shops. I will definitely be back for all my other smog checks in the future. Pricing was super affordable. This place made everything so simple. Wish other places were as easy as MM Star Smog. read more

Need a smog? Come to this place. Friendly and fast service. Clean waiting area, tv to watch and magazines. They also repair glass for vehicles. read more

I have taken my Corolla here for two things now: 1) to fix a chipped windshield (patch/repair) a year or two ago 2) to get the same car smogged, today Both times they were great. In particular, Melvin has been fantastic, super nice and mild-mannered. MMSS also has very competitive pricing, fast service, and they have a nice little waiting room too. My window repair has remained stable for a year or two, no problem. Couple that with the great reviews, which that, combined with competitive pricing, brought me to in the first place, and now I'm paying it forward. I always try to recognize great businesses when I find them. Thank Melvin & MMSS team! read more

Very quick and efficient service. They take your key and registration as you walk in, usher you into a waiting room, then call you back out in about 20 minutes with your car ready to go. Pricing is comparable to other places around, if you have a coupon. The Groupon deal costs $39, but then MM charges an additional $10 for STAR service. read more

Friendly staff, affordable price for a smog check and very quick service. Highly recommend MM Star Smog

We recently needed to have our vehicle smogged and was referred to "MN Star Smog" located on Market Street in Concord, CA.

Saw the great reviews on local Facebook page so thought I'd check out. Super fast! Clean shop and waiting room. Very convenient. I'll be back! read more

Two thumbs up for MM Star Smog, if I had more thumbs those too would be sticking up. MM had my van in & out quickly on 12/28/18 which was greatly appreciated. The place was clean, very friendly & was it an enjoyable experience. I will be a return customer, spreading the word to my family & friends. :) read more

Great place and great customer service. I got my truck smogged at some shady place on Monument and they said it failed but would make it pass for $250. I came here for a second opinion and my truck passed with flying colors. I will be back for sure..thanks guys. read more

Great smog shop, very clean, very nice and professional staff. Great waiting room. They are fairly fast as well. They took me in close to closing without any hassle and they were not gouging me on the price with a moderately older late 97 car. I had to leave a good review. I was very pleased with this shop. I just hope they don't get too busy to where I can't get in without an appointment... read more

The receptionist was very friendly and professional. I was in and out very quickly and the entire experience was super easy. Ill definitely go back for my next smog. read more

MM star smog is the best price around. I called about 10 other smog places and this was the best price of all. For my car, a 1995 Honda civic, the star smog test was $50 including the certificate. It says on the wall that it costs more, so maybe it's cuz I called ahead of time. Also, the office and waiting room are the cleanest and nicest I've ever seen at any car place. Leather seats, large flat screen tv....not that all that matters much. :) mostly the price is the best. read more

I have had 4 different smog checks at this location and have had a great experience every time.

I went here after my car failed smog at a test only facility and they weren't allowed to recommend repairs. MM was fantastic! They genuinely cared about my situation, were very professional, and were happy to check my car and explain what I needed to do to correct the issues and make it ready for re-testing the following week. I came back next week after following their advice and passed the smog test! Great prices. Great service. Couldn't ask for anything more. I will never go anywhere else. read more
