I called this one day and was given a quote of $50 cash for a speedometer calibration for my car model and speed. I call back a few days later and the price is $80 cash for the same car and speed. Both time the person was condescending and keep mentioning he only take cash and no other form of payment.A very sketchy business for sure. Would not recommend anyone going there or even calling them

I dropped & picked up owners damaged Vespa.. Upon pick up, I was amazed how well M&M did! I couldnt tell from the prior damaged area.. Just so you know, paint is 2 stage.. White w/ light blue when sun hits bike.. Excellent job!! I definitely recommend Walt (super nice guy) and his shop- 100%..

I needed to get a small dent repaired after a woman backed into my car. She recommended another bodyshop that quoted me $700, but as the dent was so small, that seemed really high. My mechanic recommended M&M instead, and they fixed it in less than a day for $400. You cant even tell it was dented. A+ service.

Im gonna give these guys a 3rd try at trying to get my speedometer correctly calibrated. God-bless their little hearts for not yet asking me for any more money hopefully they will be able to get it done correctly which I will verify by my GPS speedometer while they ride next to me demonstrating their level of proficiency

I am more than 100% satisfied with the work done from M&M Collision Inc. I brought estimates for two uninsured claims and they were taken care of like new* My car also had four or five minor dents and dings around the car but when I got my car back guess what - They were gone because these guys go the extra mile to make a happy customer! I recommend M&M to anyone in or out of town. Thank you guys for great customer service and craftsmanship!

Northern Virginias top automotive body shop. Show quality body work and paint jobs. Owner Walt is the real deal for sure!!

Absolutely the best service and people. Definitely would recommend. Thank you for your excellent service.

I have taken four cars over 25 years to M&M collision in Fairfax. Owner Walt and his team do wonderful, reasonably priced repair work, treat me well, work quickly and finish with my car looking like new. I highly recommend them.

Got a speedometer calibrated here after getting shaken down by Fairfax County. Quick, easy, and cheapest place Ive found. They use a dyno and not some GPS app on a phone. Well worth the $50

Went in for a speed calibration test recently. Was fairly quick and affordable. 5/5.

Walt is a great leader of this team. They have worked on my vintage BMW and Porsche. Walt has forgotten more about these cars and bringing them back to restoration quality then I have ever known. Just a great guy to work with and trust.

I knew Walter the owner of M&M Collision since 2013. The whole team at this center is professional, honest, trustworthy & friendly.They always got my back no matter how small or big the job is. Chantlor the Manager is also amazing. He always go the extra mile to make every customer feel valuable and appreciated. Amazing service & reasonable prices....highly recommend M&M Collision Center in Fairfax for any your car bodywork.....

Great spot to get your speedometer checked for Court.

A total paint job with minimal rock chips on the front bumper. ($2500 cash ! ) They did not even sand them down . The “new” paint is @ 2-3 years old and is chipping off. My car was there for over TWO MONTHS !!!A HORRIBLE JOB - and Worse Service ever.

Great job with my vehicle and they had a dog. 10/10.

Chandlor is awesome at M&M smart courteous responsive...

Great place, they are very straight forward and it was a nice change of pace as with most auto places I feel like I dont know what to ask for or what to do. Here however they were able to tell me in simple terms and make the whole thing painless.

Love this place!!! They always do an Excellent job on my car.. Very accommodating to your needs when you arrive.. The staff is very friendly as well ..great atmosphere all around.. I have no criticisms so far with M & M Collision and really dont expect to have any at all.. I would absolutely recommend their services to all of my friends Anytime, ..Keep up the good work!!!😊

Calibrated my speedometer for a vary fair price.

If you can, dont go there.I might be wrong, but i think it would be better to avoid them if youre a foreigner, or not speak English as an native.They may charge you for a service that seems is not done, or not required, or charge you more than level of the job.I gave them w stars only because they are fast service.

They did an awesome job with my cars speedometer calibration. Probably wouldnt recommend to those that dont like dogs though as they had two medium/large dogs roaming around when I went, which seems to be the norm. They are friendly and I love dogs, so I actually enjoyed playing with then while I waited.

They were able to take my car on the same day as calling and gave my a qoute right as I got there! All the staff was very friendly and understanding and did their best to give me the best deal. I really felt taken care of and cared for! I would recommend them to anyone!

Referred to these guys by word of mouth through a local mechanic. They were honest with the repair, considerate of my schedule, and knowledgeable about all the intricacies related to vehicle body work.

I had a deep chip in my paint, all the way down to the frame. I took my car into 6 different places around the NoVA area and was told that it would cost from 350-400 dollars and they would need to repaint the entire door and pop out the dent. It is a new car, so I wanted the work done right but I am also a grad student and I am super tight on cash. My Hyundai dealer recommended I go here and I am glad they did. I worked with an older gentleman who although was very laid back, did a great job for only 300 dollars. The color matches right, the door was painted well with no imperfections and he even washed my car and tires. The only complaint I would have is the white dust not wiped off the inner door or the interior of the car but I think that was because I came to pick up the car pretty early. The car was finished by the time he had said and there were no problems.I was very scared because this was the first time I was dealing with these issues but I will go back to M&M again because I think they are honest and fair with their pricing and they did a good job on my car. They also seem to take pride in what they do and that means a lot.

I have had my vehicle repaired by them 3 times and each time M&M has gone above and beyond. They are very helpful and do a great job. My car looks like new again!

These guys have the best prices I was able to find. They did what they promised and they finished quickly. There isnt anything not to like, they are a top notch shop. You can get a rental car on-site at a good rate which makes things easier.

Top notch dent work. Quick, Professional, Honest. Thanks so much~

I wanted my rims painted, they went above and beyond my expectations. Thanks M & M Collision.

Ive been coming here for over ten years now for a variety of work, from repairing bumpers and little projects up to a whole repaint of a classic BMW. Walt and his the staff are personable, competent and reasonably priced...thats a trifecta youll rarely find in any service shop. For any auto body needs, or just to informally meet Walt in person before you may need anything, I encourage you to drop by. They are just west of Fairfax Circle.

Very confused why when I call for an estimate to have my speedometer calibrated it costs $75 yet when my dad calls the exact same day about the exact same car, it costs him $50. It angers me that a company thinks they can get away with treating young women like this.

Whoever I spoke to when I called was RUDE... I got a speeding ticket and was referred by my attorney to get my speedometer calibrated. He gave me M&M Collision’s info and said it’ll be 80 bucks and cash only. Thought that was a little strange but decided to call and set an appointment. The guy I spoke to was extremely rude from the beginning. He asked how fast I was going (I guess because the faster the more they charge) and when I told him it was a reckless 91 he said oh that’s gonna be a 100. I told him my attorney said it was 80 cash and he fired back “Oh we’ll it can be 120”.. That’s not how you talk to people/ a potential customer. I hung up and court went good without this junk shops help.. STAY AWAY

Excellent job, you cant even tell there was anything wrong with my car in the first place.

I absolutely hated the experience. First, the guy driving my car almost ran it off the thing it was being tested on multiple times which scared me. Second, the results I was given were Incorect so I wasted money coming here. Staff is okay. I do not recommend coming here

Color match was way off on my space gray bmw, my Galaxy s4 camera could pick it up easily. I was told they have a color match machine and blending wont be needed, which didnt make sense because its always needed, but I went ahead with them. When I got the car back half my driver door was blended the wrong color. The owner couldnt see the difference between their paint and the original paint but my phone and everyone on the Internet could. They did procrastinate alot. Two of my tires had nails in them after leaving here. One redeeming quality is that he was polite. I dont have a sharp eye and I cant see most of the things people in this business can but the owner is blind.They also seem to be reviewing the self because some of the people that have left reviews I have seen working in this shop.

Courteous staff, prompt attention to issue, fair pricing, very happy with experience

I have my car speed calibrated, done in 15-20 minutes .

Perfect customer service!! Highly recommend!

Went here to get some body work done on my car after I got hit, and they did a great job handling everything. When I got home, there was one issue still, so I brought it in and they helped me immediately at no charge.

The best by far in Northern Virginia.

Quick and no nonsense.

They are a waste of time. They procrastinate too much.

Fantastic Service!!

Cooperative staff.

Great owner, friendly atmosphere

I visited the hertz people inside this office. The person was not there most of the time. The people from the collision company were also not really friendly and we had to wait outside.

HONEST Business

Great dogs!

Great service!!
