They only do emissions tests in the morning, which I didn't know, but the guy was very helpful, suggested other places and even helped me get a temporary extension on my registration. Will be taking my car here when it needs repairs.

Very organized as far as emissions goes. Went in, signed in and waited. When it was my turn it took about 4 minutes for emissions test to be completed and I was on my way.

Went here for my emissions test, and they were very helpful! Even helped me get a corroded license plate off my vehicle free of charge. I very much appreciate that level of service, and will visit again.

Come at 8:30am for emissions test and get it done at 9:40am. You just need to wait. staff is nice, but don’t pick the busy hours. Emission test from 9 am to 2 pm.

Very rude and disrespectful when in on a Wednesday to get emissions at 4 o'clock they don't close till 5 but nobody wanted to do. A mission's testing tell me come back tomorrow morning so I come back today and they tell me by appointment only careless carelessness and it only takes not. Even 5 minutes. To hook up the little box to the car and run the test

Absolutely the most friendly staff I've met I needed a emissions test done in the young lady behind the counter told me they don't do emissions test this late during the day but she was so sweet she said pull your truck around to the side door and I'll get you done I'm so grateful for her kindness I highly recommend this business but if you're going to get an emissions test done you need to be there early in the morning like 7:30 cuz they open at 8:00 a.m. I don't remember that lady's name but I give her a big hug if I could see her absolutely a beautiful business with very kind service

Bad experience. I walked in to sign up for the emission test at 12 noon. Its been an hour and there were no calls. They told me they called me twice but i didnt answer. Unfortunately, they called the wrong number. So they erased me on the list right away and put me again on a new list. Oh my God. I waited forever for my turn. 🥲

Not a place i would go back to ever 🤦 was told to park and wait for call for emissions but never got the call. Wasted hr watching people pull up and go in and out 🤦 i guess you have to be family or close friend idk but sure was unprofessional to have high ratings. Thanks to another shop 7 min away i was in and out no problems no wait 💯

Customer service needs to be improved. The lady had a bad attitude toward her customers. They only accept customers for a limited time in the morning, so they should make more appointments available and/or accept walk-ins like other car shops.

Very unprofessional. When calling about scheduling emissions test I was told “show up tomorrow morning an hour before opening so I could wait outside and get it done” after waiting in line an hour the finally told me I needed to come back tomorrow show up earlier and wait outside in the cold so I could go in schedule the appointment and then continue to wait.I strongly recommend they get a bilingual employee to handle calls

I first went to them for emissions testing and was impressed by how fast they were. So I went back for a transmission fluid change and they were fast and reasonable especially since I came in WITHOUT an appointment. Unfortunately I had issues with my bearings and they got my car repaired same day. I have the worst luck because I also became a victim of Milwaukee's infamous potholes and they have been so reasonable to work with despite my insurance company being slow and difficult. I rarely give reviews on businesses but these guys earned it. you can tell the owner Wally loves his job he loves coming to work and actually helping people he has been extremely reasonable and patient with me over my current issue of getting my car repaired I'm very confident that these guys are going to get it fixed and get it fixed very quickly I have never had an issue with these guys and I'm very confident to recommend their services to other people because Wally seems to be very professional and focused on helping the community. I literally have nothing negative to say about him or his business. I have seen that people have complained about the diagnostic testing and I totally understand from a business standpoint why they do it. They don't charge unless you do the repair at their place I think this prevents people from trying to get a free diagnostic and get their "friend who works on cars" to do it.

I took my van in for emissions. Great fast customer service. You dont have to wait in a long line. All you have to do is go in give your vehicle information and phone number. Then patiently wait in your car until you receive a call that its your turn. I found this very convenient compared to other places where you have to wait in line for hours sometimes to get emissions service. I was out of there in about 20 minutes tops.

Charged me seventy dollars for a tow, diagnosed a bad alternator that he could fix for 600 hundred dollars, ( what a joke ) Had him tow it somewhere else for seventy dollars more, before he let my car down, he let me know.It's gonna be ten dollars more. He tried justifying the $10 by saying he did diagnostics and other stuff for me.But the whole time he was offering me the diagnostics.He said he was doing that for free. These people do business with a crossed tongue, for the $150 that I paid for the toe $70 there.$70 back and the $10 that he ripped me off.I could have got an alternator for a coule hundred dollars and just fixed my problem. Thank God they didn't do it.I was able to find someone that was going to do it for seventy 75 dollars. To sum it up with the $150 that they ripped me off and the $75 that it costs to get it fixed.I still saved three hundred and seventy five dollars.
