I dont know how to put into words, just how amazing these guys are! I was searching for months to find a place to fix my exhaust manifold issues, no one wanted to do it because of how much trouble it would be, I even had a place keep my vehicle for a week and they decided it was too much work. I was given quotes as high as $2,300. I took it to J & S and dropped my vehicle off Tuesday morning, had it back Wednesday evening and I paid nowhere near $2,300. J & S did an amazing job on my vehicle, any work that I cant do myself, I will take to them and I would highly recommend them to others.

J & S is nothing but great service and honesty. Jim will tell you if your car is worth repairing, and help you work things out if it isnt. If it is, you can expect prompt service that ensures your woes are resolved. Cannot recommend J & S enough.

Best mechanic Ive ever encountered. Very friendly and professional. Definitely coming back if I have car trouble.

I have not lived in the Milwaukee area very long, but I am glad that I decided to bring my Cruze here. Jim is an honest person and explained everything very well. He took care of me and I will bring my car here whenever I need work done. Will definitely recommend people to bring their vehicle here if they are in need of repairs. Could not be happier

Very nice place... Super awesome work and friendly service 🤩

I got halfway through replacing the front subframe on my car and rounded/snapped a handful of bolts. I decided to give J&S a call to see if they would help. The owner told me he was crazy enough to try. They were able to complete the repair, help me identify other problems that the car was having, and even replaced an indicator bulb and topped off the fluids for me. I absolutely reccomend taking your car here if you want honest professionals to help you with your car.

Great service and great people.

So nice, honest and reasonable!!

Excellent place to take your car. Family owned.Very trustworthy! Ask for Jim.

Great place to take your vehicle. Very honest and reliable. Jim and his team are awesome!!!

Jim is one of the most honest mechanics you will ever meet. Ive been going to him for almost 2 years now and Ive sent a handful of friends. All of us only have good things to say about him and his crew! Will not take my car anywhere else.

I dont take my cars anywhere else. These guys are simply the best in town and have reasonable prices.They have checked out my cars and actually undersold work, telling me You can avoid having this done for a while, the part still has life in it(And still be safe). This was incredibly refreshing to hear. Every other auto repair place in town are always trying to up sell everything. Jim and the guys are honest.

Best. Mechanic. Ever. Jim is the most honest, reasonably priced mechanic I have ever been to. Not only that, is they go through great lengths to make sure your car is running safely and like a fine tuned machine. The guys there are always friendly, and the owner, Jim, is one of the nicest guys youll ever meet. I recommend this place to everyone!

Jim is the most caring, honest and knowledgable mechanic I know. Very efficient. I would recommend this auto repair shop to EVERYONE!

I can’t imagine anyone having a problem doing business with Jim Diehl, owner of J&S Accel. My car repair guy now for over 30 years, Jim is a personable hands-on business man and mechanic who works alongside employees in his shop. Jim takes time to explain things before proceeding with work. With numerous years of experience, Jim is extremely knowledgeable regarding diagnosis and repair. He provides fair estimate of costs and telephones or consults with his customers when additional problems are found. Customers are free to decline recommended services. Jim’s goal is to have customers NOT spend money on auto parts and services except for what in fact is needed.

Best mechanic in town! Jim is always honest & fair. Hell try & fit you in, even if hes busy. Theyre all pretty fast, efficient, & thorough. Great atmosphere. I wouldnt go anywhere else, for even an oil change!

Honest mechanics are hard to find, which is why my wife and I drive 20 miles past lots of other garages to visit this guy. Not the cheapest, but not overly expensive either. This place is insanely busy.We have local garages to handle scheduled oil changes and tires, but this is the guy for hard to diagnose or advanced or extensive work.The waiting room is unusually clean and interestingly decorated.

Jim is awesome. Been going to him for 15 years.

Great service and great price. Only place in town I take my car to now. Only downside is no nuts for winter storage.

I actually didnt have a chance to make the appointment setup by Jim (due to the criticality of the issue), but he was able to help me out greatly regardless of me taking it in. He took the time to research a bit and do a follow-up even outside of me coming in. Top notch communication and friendliness. Would recommend to anyone.

Jim is an excellent mechanic and a fair businessman. He has helped my family and I many times and I remain grateful.

Always great service. Honest and very reliable. Prices are always reasonable and everything being done is explained.

J &S helped me after I had a terrible experience at Breager Ford. Breager didnt finish some warranty work, then wanted $135 just to diagnose the problem. I brought it here and they diagnosed it and fixed it for me. I will be coming back. Great people. Great job.

I have been going to Jim for service and referring customers for over 30 years. He does exceptional work and is very reasonable and fair. He is the BEST mechanic I know and a real pleasure to work with. He goes above and beyond in his honest service he provides and I recommend him highly and exclusively.

Jim does an excellent job with my repairs

Best in town for fixing cars need your car fixed go here you will get a great deal no lie

By far the best mechanic I’ve ever dealt with. Quick, honest service at fair pricing. Car repair anxiety is gone with these guys in town.

Honest and reasonable good people!!

Nice family shop. Good work. Fair pricing. You better really be ok with Jesus though when you enter the lobby.

Our business one ton van door want closing, now it does, the interior lights were fixed and our front end was not driving straight.. Jim and his crew fixed all this for a reasonable rate.. Excellent work!

He is great and honest, fair pricing

Jim is one of the nicest guys around and an extraordinarily honest and capable mechanic. Its really great to have a shop you can trust.

Jim the owner is a kind and likable guy for sure, he sat with me and explained and talked about engines with me for longer than he had to and answered all of my questions. Reason I dont plan on coming back and for the low rating is he never okayed my repair with me. Im broke as a joke and he went ahead and did $700 worth of repairs/labor without calling me to ask if he should go ahead...and it didnt help the problem at all. I had a cylinder 5 misfire in a Pentastar engine. They replaced some spark plugs and coil packs - the last guy who owned the car did the same- J&S could see that the parts were like new, but replaced them anyways. In the end, I bought a used engine with 40k miles on it for $1300 and replaced it myself in my driveway for free. It wasnt that hard- just label everything carefully and take pics/video. Saved myself about $3500 from the quoted engine replacement cost!Maybe I just dont understand the auto-mechanic industry and how it works and Im the one whos in the wrong, but it left a bad taste in my mouth either way.

Jim is very polite and the mechanics do a wonderful job on our vehicles and when you walk into his office it is so relaxing it makes you feel like youre at home I just love his place

Theyre up-front, polite, timely, and fairly-priced. What they arent is convenient to drop-offs and emergencies; theyre perpetually swamped, and I had trouble finding an appointment any time sooner than 3 days in advance. It says good things about their demand, but it does pose logistic problems.The first thing they did for me, an alignment (among other things), was a bit shonky, but I suspect thats just my old Hyundai being stubborn.

Very impressed. Quick repair, honest pricing and very kind. I will be going to J&S Accel for all my repair needs.

Small garage but the owner has a big heart. Great service. I recommend J & S with no reservations.
