Worked with Steve, didn't end up buying but he was super nice and upfront with us. A much better experience than some of the dealers we talked to on this journey.
Favorite car I have owned, to date!
The Yukon checked all of my needs, I have plenty of room for my children and my Great Danes. I enjoy driving the Yukon and how it handles, overall love this vehicle!

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

Second Car We Purchased Here
This is the second used car we have purchased here. We like that they post a link to the carfax on their website. That allows us to research the cars we are interested in before going for a test-drive. These are not auction cars but decent trade-in cars. The buying process is straight forward. They performed a safety check, changed the oil and gave us new brakes all around. We will be back when we need another!
Great truck, solid engine, comfortable, smooth, and it

Amazing Experience!
I have bought from Peter a few times over the years with great results! He is a true professional and I trust his expertise completely. He is the first person I go to with any auto needs and he always has the answers. Wholeheartedly recommend!
Great truck with some bad
It is a great truck with great capabilities! although i must say, some of the technology in this car has its low points. Center stack tends to not cooperate during bluetooth pairing and the headlights have poor illumination to the point i had to retrofit LED bulbs for better visibility. Overall very comfortable ride and smooth drive

Great Experience
Such a great experience buying a car from Charlie at Shamrock Motors. Within 24 hours we were driving it off the lot. The no hassle prices made the purchase less stressful and Charlie was so fun to work with. Next time we are in the market for a car Shamrock will be the first place we look!

Great truck for a great price;
Rick was awesome, had the truck I wanted to look at ready to go when I arrived for my appointment. He was friendly and knowledge and made the buying process way less painless than a large dealership does. Highly recommend them if your looking for a quality used car.
My 2016 GMC Sierra 1500 SLT All Terrain - Love it!
I've owned this GMC Sierra 1500 All Terrain since it was 8 months old. With the exception of two warranty issues (failing power brake vacuum pump and transmission electrical harness), I have been totally happy with this truck. Up until now, my 1996 Chevrolet K1500 Silverado with it's 5.7L Vortec engine was my favorite truck of all time, this GMC (5.3L LS engine, 8 speed automatice) has earned the top spot now of my all time favorite truck. It is comfortable to drive, and runs as good as the day I bought it over 5+ years ago. I've got 71.5K miles on it. My biggest issue is I wished it had the 6.2L engine for better towing capabilities. Other than that ... love this truck.

Failed transmission and full replacement
We have owned our GMC Sierra 1500 for approximately 9 years now. The only real disappointment with the vehicle is that we had to have a full transmission replacement Just after the 100k mile without any warning whatsoever. The truck now has 107k miles on it and now , again out of nowhere, we are experiencing slipping in the trans and the engine light is now flashing. Very disappointing since we are starting to feel uncertain about the reliability of the vehicle now. The truck itself is gorgeous and shows ZERO signs of its age, sporting new rims and tires and a lifted body and no rust on the body at all. We hope there are no major issues with the engine as the vehicle has always been maintained as needed and on time for regular servicing at the dealership.

I bought my gmc sierra in 2009 , brand new, and it’s the best truck that I have ever owned, and I have tried a lot of nice trucks, I mean i have owned a truck, Ford used to be my favorite , but it doesn’t even stand a chance up next to a gmc sierra like mine, my brother in-laws were very jealous about me owning it, my brothers all liked it, I have had a lot of pleasure driving my truck, and I have had very little problems with it, I’m retired now or i would buy another one just like it, gmc is the premier truck, it’s the very best, i love my truck.

Best Dealer For Ioniq 5
Just bought a 2022 Ioniq 5 from Shaker Hyundai. Paul C was incredibly helpful, knowledgeable and patient throughout the process. This was my first new car purchase (at 60yo!!) and this is a very technologically complicated vehicle. A 2nd Ioniq certified salesman spent about 45 minutes walking me through every aspect. There were horror stories of dealers upselling this car for thousands more than MSRP but my price was exactly what I expected. Highly recommend the car and dealer.
Its a decent car, but on a car frame.

Fantastic Experience
Had a great experience buying a used car here. Everyone I dealt with was friendly and knowledgeable. I never felt pressured, and being a single female, that was important to me. They gave me a fair price on my trade-in, and their cars are reasonably priced. Will Anderson was a terrific sales guy, and Jill and Matt guided me through all the paperwork. *Highly* recommend this dealership!

A satisfying (used car) purchase experience!
Was looking to replace my 2007 Ford Escape. Liked the looks of both the Nissan Rouge, and the Mazda CX-5. Had checked out a Rouge, but wasn't sure on it, then while at work I was checking out local dealers and Schaller Honda popped up. They had a 2014 Mazda CX-5 with about 80,000 miles on it. Went over at lunch time met with Xhoel Lolocaj he showed me the Mazda CX-5, took me out for a test drive, came back and then we started on the paperwork. Xhoel had just started working there the week before, but he was very professional in all of the steps of the process. After Xhoel helped me, he brought me over to finance where Frank Williams helped me complete my purchase of my new car, I had a bunch of work on my end to get money, checks and deposits figured out. Both Xhoel and Frank were vey helpful and patient while I made things on my end work out.
Perfect for us!
As we age, our reaction time may become slower. This vehicle is loaded with features that make me a safer driver. It connects wirelessly with my iPhone for hands-free Apple CarPlay. Love that! And the Acadia is a dream to drive. It’s the perfect size for me and my family

Lou was my salesperson and he was super communicative, explaining and re-explaining when he seemed to feel it was needed. No surprises along the way, I was able to test drive the van as much or as long as I wanted, have a mechanic come by to inspect it and they washed it and added a full tank of gas on pickup day. They had done some quality servicing to the vehicle as well before pickup day. Lou mentioned early on that he wasn't paid on a commission basis, which was a good detail for me to know. In the end, all the numbers were the same from the beginning to end, no "uh oh" moments and it was a super fast experience on pickup day - probably the fastest ever for me to get the keys and drive a new (to me) vehicle home. I will look to use them again if possible in the next year or so. Highly recommend.

Great Pick-up
Bought this 2016 GMC Canyon (4cyl) at car max in 2017 . It was part of a commercial fleet and was well taken care of and low mileage . I’ve only have had one problem and that was in the engine cooling system where I had to replace two hoses and a goose neck . While repairing that I noticed an oil leak around the valve cover so I replaced the gasket . It was under warranty still ( just happened in Jan 2024 ) . I could have repaired it myself but who wants to get all dirty when it can be repaired by GMC at little or no cost to me. It still has 6 months remaining on warranty ( I did purchase from CarMax) hoping it does not need any further repairs . It is 8 years old and according to its records this is the first repair other than natural repair items that had ever been needed . It rides well pulls my utility trailer fully loaded just fine . I also have a 2000 Ranger that I had to replace the tranny on when it was just a few years old . It has never needed any other work. I believe the GMC will last me for years to come . But you never know so I will be buying another after market warranty on it when the time comes . I’ve already added that to a 2015 vehicle I own who’s warranty had expired . I’m a old school mechanic I can repair olde vehicles easily ( compared to todays ) I’m also a former Turbo Prop Mechanic from the Air Force and worked those motors for almost 29 years . I had worked on Piston Air Craft Motors for a few years before the change . A lot like a car piston motor in many ways . Two kinds of piston motors on Air Craft . Line a cars block or a receptacating motor( Round) . Very easy to trouble shoot vs Turbo Prop. Just letting you know that I have experience as a mechanic and know a real problem vehicle when I see one . Would buy a GMC canyon again or maybe go larger due to my new 42 foot long Camper I have rec bought .

I had an outstanding experience purchasing my Cadillac
I had an outstanding experience purchasing my Cadillac Lyriq from Blasius Cadillac. Despite having researched the vehicle extensively through YouTube videos, sales representative Rich Noble took the time to thoroughly explain every detail during my test drive, ensuring I fully understood all the features. When I arrived late due to travel delays from Boston and a previous dealership appointment, the team was incredibly accommodating and flexible with my schedule. The pricing process was refreshingly transparent—we negotiated the complete out-the-door price entirely through email with no hidden fees or last-minute surprises. Most impressively, they coordinated with the Massachusetts RMV and delivered my vehicle directly to my home with plates and registration paperwork already completed, saving me an additional trip back to the dealership. Blasius Cadillac demonstrated professionalism, transparency, and genuine customer care throughout the entire process. Highly recommended!
Reliable and Thrifty!
Good MPG'S with the four cylinder, smooth 6 speed automatic transmission. Very good sound system with bluetooth. Very reliable, just oil changes and tire rotations. Would buy again!

Love Our New 2023 Denali Terrain!
We purchased the Denali Terrain 2023. The car is great. I have had four knee surgeries and needed a car to get in and out easily and comfort seating. The controls for adjusting the seat just the way you like are great. I am troubled also by back problems and totally love the heated seat when needed. Sometimes I just want to ride around and turn the heat on and adjust seat so my back feels better. The different controls and are numerous. I love the safety control warnings and info with traffic. The screen is fabulous and helps so much. When ever I park I like to drive in and park and then hold on brake put it in reverse so the screen then comes on and shows how I parked. I like the levers in cargo area for putting seats down and also like how flat they sit. Plenty of room. The back seat is roomy even when person in front is back. Enjoy being up higher than a vehicle. I feel I can see more and it also makes me feel safer. The Terrain looks beautiful and love all the chrome in front. The car seems bumpy but not as bad as our last. The roads are in rough shape here. It has a lot of pick-up my husband demonstrated that to me and he wont be doing that again unless it is necessary. It is a turbo 4 cylinder and can not believe the power you feel. All in all Iove the car and getting good mileage. Purchased car from Boucher in Waukesha. They were not pushy. Explained everything in detail and were very fair. Great place to purchase!
