    Amazing they did so good! cleaned my car inside out. They were very sweet and they took their time. My car looks amazing.

    Not sure if you can see this dirty hood.  Terrible work.

    This place has changed their name so my 2 other negative reviews don't show on here. Well this place is still a terrible place to get your car washed. The owner is pretty rude if you have to speak with him. My wife had a dispute over pricing, he refunded her the difference but was super rude about it even though he was in the wrong. In the end the car wash was sub standard. Car was not fully cleaned and they left water spots on all the windows. If your going to charges $50+ for a car wash at least get the basics down. Stay away from this place.

    I randomly passed by this Car Wash and my SUV had some hard water stains that needed to be removed. I explained to the employee that the hard water stains were my main concern. They start with a powerwash rinse and then they take it through a car wash machine, and their staff hand dries it. It cost around $30, but I was a bit disappointed when they were done the hard water stains were still there. I pointed it out to them, and they said they couldn't remove it and that I'd have to take it to a shop to get buffed out... I ended up going to a store later and buying Water Spot Remover Spray that was only $15 and that worked in removing the water stains! I should have done that in the first place. In conclusion, if you have hard water stains don't come here, just buy the spray lol I feel like this car wash is good if your car is just dusty but I think their powerwasher is too weak for a heavier job. I don't think the $30ish price tag was worth the wash since my SUV still wasn't clean. Their staff was really nice though so that's a plus.

    They tour my driver seat, floor and mat out of the car and ripped my carpet, denying that they did it

    Brought in my truck to be detailed at a total price of $50 spots throughout the vehicle that's not the biggest problem at all. The gentleman asked me if I should get my car mats Wash and I said yes they basically tore my front driver seat carpet and tore the mat right out of the car and denied tearing it nor did he say that he would fix it. See pictures.

    Gotta see if I can get this buffed out now.. ‍

    Absolutely no value in this $80 wash and wax service.. I ain't ever coming back! swirls all over my brand new car! and I had to wipe so much risidual wax left behind? Horrible quality job nice people just not coming back.

    This is my last and final time trying to make this car wash work. It's so convenient to be close to home but the price and service they give you is AWFUL. $55 for a 23 minute car wash. And crap everywhere still on my car. Windows still wet, inside still dirty!! What did I just pay for ? Horrible service. Finally learned my lesson and will not be back. Drive down Clayton road for better service.

    See all

    Zach is the best!!! Love this car wash so convenient go here asap ! The best in concordread more

    If you go here you better get the membership, because the difference between the cost of a wash…read moreversus the cost of a membership is pretty small. Will also need the unlimited washes because the car wash SUCKS! It took two trips (back to back) thru the wash to get my dirty car even close to clean. If you go once or twice a week, then the wash is fine but if your car is dirty, it will take a few runs to get it clean. The best part of the car wash was the vacuum and towel stations, so that you can dry off any drips, vacuum the car and wipe down the inside too. Problem is that the vacuum stations fill up quickly so unless you go at odd times you will have to wait or go without. The last straw for me was when I noticed a swirly scratch on the back of my wife's car and then saw the same pattern after a wash on my car. I was washing twice a week and I am 99% sure that it was the car wash doing it. I showed the workers so that they could fix the issue, but they totally denied that it could be the car wash. When I explained that I was just informing them and didn't want anything other than them to fix it, they still denied it. I then explained that both our cars have the same type of swirly scratches and I know it wasn't there on my car two days before, they still denied it could be the wash. I said ok, drove home and canceled our membership. Haven't been back since and haven't seen any more mystery swirly scratches on my car.

Visit #1: There was no attendant anywhere, which I understand -- you can't staff a place 24 hours a day. But right where you drive in there was a piece of plywood with a nail sticking straight up. Anyone could have punctured a tire. Maybe that's not technically the car wash's fault, but someone in this neighborhood thought it was fine to leave it sitting right there in the entrance. Visit #2: I was vacuuming my car and had just set my glasses, pen, and notepad down on the concrete by the vacuum stand for a moment while I worked. Within seconds the attendant came up behind me and grabbed them to throw them into the garbage, which was honestly kind of shocking. I had to stop him and explain they were mine. His response was basically that I "shouldn't put things there." But I had literally just set them down next to my open car door while vacuuming -- they were clearly personal belongings, not garbage. Visit #3 (today): While I was vacuuming my freshly cleaned car, the attendant's pug jumped straight into my car with muddy paws and ran across my seats and center console. I do want to say the attendant himself was friendly and said good morning to me that day, and he seemed like a genuinely kind person. I'm not trying to get anyone in trouble -- in fact he seems like someone who could be a real asset to the business. But it might be worth management simply reminding staff that dogs should not be running loose in a parking lot with moving cars or jumping into customers' vehicles. That was the final straw. I don't expect perfection, but basic awareness and common sense go a long way. A small dog shouldn't be running loose in a parking lot with moving cars, and it definitely shouldn't be jumping into customers' vehicles. Three visits, three completely avoidable problems. Unfortunately, that's enough for me. I'm sure this review won't do anything to your business, but for what it's worth there are also some basic things missing here. For example, there are no clips in the wash bays to hang floor mats, which is pretty standard at most self-serve car washes. It's actually one of the reasons I don't wash my car here and only use the vacuums, because trying to wash mats without them is frustrating. It's just another small thing that adds to the overall picture where there always seems to be some new problem or omission you'd think would be standardized by common sense -- but this is California.

    My car was so dirty that someone wrote, "wash me."…read more I normally go to that place in WC, close to Target and the Land Rover dealership, you know, the one where you have to walk through that weird space. Obviously, they were mediocre as I have never had the desire to write a review and I can't remember their name. Anyhoo, Superstation got my car looking brand new!! At least I feel that way! I don't know if it's my imagination but my A/C is working wayyyy better!!! They cleaned my car so well in that hot ass heat!! For some reason I asked the attendee If they split tips. He told me that the people who vacuum your car aren't included. For the Carwash plus 20 dollar tip It's sooooooo worth it!! Don't be a cheapskate !! Give 10$ to the people who vacuum and 10$ to the people that wash your car's windows/put on tire spray. I think my wheels were cleaned so well they squeak? I couldn't care less as the amount of care they put into my ride was worth it!! I Highly recommend!!

I've had ok service here before, not GREAT just ok. Today I needed a deep clean detail and I had them do "the works" detail on my car before and it was really clean that time. So, I decided to use them again. (I told the lady I wanted it shampooed three separate times.) My car was very dirty. I transport my golden Retrievers around alot, so it is a dirty fur bomb golden hairnado inside. So, I got there before 2pm today and they had cones set up blocking the entrance. That was strange, I thought they closed at 5pm??????? Anyway, the lady motions me to drive on in. So, I drive in and ask them if they were closing because I could come back another day. She told me "no we can take you. We close at 5 but we were going home early today because business was slow." I told her my car was really dirty and furry, she said "no problem, we'll take care of you." She also told me that since I had been there 11 times before, that I would get a discount. GREAT!! Take my money...lol. So I left my key fob in the car and went inside to pay and I also bought a bottle of water because it was going to be an hour or so for the detailing/shampooing. 20 minutes later my car rolls out and under the shade trees. Two workers started slapping towels all over my car, just rubbing and quickly drying...I thought that was odd. I was waiting to see them roll a utility cart out with detail cleaning supplies, well the utility cart never roll out. 25 minutes from the time I left my key fob in the car to "finished"...LOOK AT THESE PHOTOS and you be the judge if it was "finished"! It was not closing time, it was only 2:25pm. The dude called out my car because they were done. I was shocked and could not believe they were "done". I looked at the dirty seats, the dog hair was still in my carpets and the back window dash board, the windows were all smudged, the cup holders remained gross, and you can still see where earlier in the week where the mechanics greasy bums sat on my seats and got grime everywhere. The wheels don't even look washed. The worker was clearly mad I was criticizing this crappy work and begrudgingly went and got some kind of long hose from the back and began power blowing all over the inside of my car and then the hairnados went WILD all over the inside of my car ...LOOOOOK AT THESE PHOTOS!!! I'll not EVER go back there again!! I SHOULD HAVE LISTENED TO MY HUSBAND and not taken my car here!!
