Extremely satisfied.
I have to say this was a great first time experience for me and my family. Rich is the best he made us feel like family he knew exactly what we need. The guys in the office were just as nice. Our family now has a great car that's just perfect for us. The whole presses was painless thanks to everyone's help. The only thing missing was a Sunday dinner. I would recommend Rich and the guys to anyone I care about. I can't wait to do business with them again. The best around.
The gmc Yukon from 2014 is very good it’s good for snow
The gmc Yukon from 2014 is very good it’s good for snow hauling trailers and children. What I love is the cozy luxury interior with the leather seats. It is very reliable the biggest problem we had was the cooling system failing but the repair cost was only $200. I kept everything on it stock. The sound system speakers are crazy good the base is 200% good I just love everything about it!

Awesome
I cant say enough about how great this experience was. I went to dealerships, and was given wrong information, pushed, manipulated. Here at Capital Motors, it was so different. They were honest, no extra fees, everything was smooth and easy. I highly recommended going here if you're looking for a car.
My Work horse.
I brought this truck in 2019. I kept taking it back to the dealership to get tweaked several times. Once it was figured out, never got any problems ever again. A little weak on the power side, but, other than that, its a magnificent vehicle. A total work horse. Great on gas. It is totally worth it.

Buying a used car from Hertz was made very easy by Jeremy W. in Smithtown, Drove my new car home that same day. Very happy with my purchase, car drives great. Would have given 5 star and will change all to 5 star when I am given the extra key and booklet. The only snag in the purchase was I was given one key and no booklet for the car. Jeremy claims he has ordered both for me, Thank you Jeremy.

I always bought the GMC Acadia (4 times) but decided to try the terrain. I absolutely love it and it's a great car for zipping around in town. I would take it for a weekend trip but not on a long trip as it doesn't have a lot of cab room, but for two people it is fine

A small but professional dealership
Dan and Nick were good to work with. Recently purchased a Volvo. When I test drove the car there were a few issue as most used cars have. They had each issued fixed when I picked up the SUV.
2006 gmc yukon denali xl.
My favorite car I have ever owned. I've had cars, trucks and a couple of small suv type vehicles. I thought it would feel like a big blazer. And boy oh boy was I wrong. I bought it ar 180,000 miles and it drives like a dream. All the power I could ever ask for. A bigger engine than my camaro had and almost as fast. My kids love it, I love it the wife hates the mpg but if we have a snow storm we take the denali, when we have the 4 kids me and mom and we can still fit another adult and any and all luggage. What is there to complain about. It's reliable and when you expect the instrument cluster panel to be wonky from bad wiring. Well it's nothing that stops me from getting where I want to go everytime. I love the vehicle and hope to keep it for a very long time.

Best experience buying a vehicle!
My husband purchased a truck a few weeks ago from JTL in selden and it was the best experience we’ve had at any dealership in years. Everyone there was patient and really accommodating, we had some hiccups while getting approved for a loan but they helped us in any way they could, all while making sure we were still comfortable with the payments we’d have to make. The truck is exactly what my husband wanted and everything about this process was amazing, thank you JTL!
Awesome car!
Awesome car! Reliable and I have 200,000 miles on mine and never had a major repair. Comfortable. Good for towing. Easy to hold a lot of people. Speaker quality is good. I’ve owned about 6 different cars and this is my favorite by far.

They were excellent
Very kind, professional and most important FAIR! I was extremely stressed over my car situation and it was a weight lifted off my shoulders! Down to earth and extremely understanding! I am very satisfied and will reccomend them to those in need of a vehicle
Headlights are terrible. Plexiglass scratches!
Love my yukon, but not the plexiglass headlights. You can not clean them to get them clear. It really is a safety hazard for night driving. The film on the headlights blurs the light output. The cost to replace them in ridiculous!

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.

Happy Buyer
Customer service was pretty good. They have a lot of good vehicles which made it hard to choose. I bought a Subaru Outback. I dealt with Ed the general manager. He made sure I was happy and gave me the best deal possible. I'd recommend this place to others. I'll definitely buy from here again!!
An AWESOME Vehicle!
This wasn't the vehicle I'd gone to the lot to see... But it was parked 2 vehicles down, and the price was $3000 cheaper!! It even has more bells and whistles than the Toyota I'd initially planned on getting. Awesomeness!!

A Second Choice
Over a year ago I purchased a Nissan Altima from capital motors and still enjoy driving it every day. Because of the nature of my job It is necessary to have a back up vehicle. I had a Town&Country since 2004 which recently died and I needed to replace it. My first thought was to look at the inventory at Capital Motors and they had Ford Escape which looked good and affordable price. ERIN and Nick were very friendly and helped me with my second purchase. This car is also a joy to drive. Thank you again to Erin and to Nick. - Joseph Raffaele
Love love LOVE
I have owned my Terrain for 3 months now, and am absolutely in love with it. Super smooth, great pick up, and I get a lot of complements on both the exterior and interior design. I average 26.3 MPG city and highway combined, which is not bad considering I live in Florida so my AC is never off in the car.

Bought my 4Runner
Bought my 2018 4Runner from them. Good "No haggle" price. In spite of the "Covid" restrictions the process went smoothly. Their "Detail Center" was closed due to the restrictions so they gave me a "We owe" on the cleaning and detail.
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!

Beautiful truck
Vehicle is very nice and has all the bells and whistles. I bought it to pull a 26 ft Airstream and it does the job but not great, could use more power for towing. It is difficult now to find a vehicle to pull a large trailer. I didn't want a pickup because I haul a large dog that takes up the entire back seat. I wish they still made the 3 quarter ton Yukon with the larger motor like I used to have. You could haul anything with it. The Yukon XL with the 6.2 motor just barely does the job.

Wow, I truly can't say enough good things about this
Wow, I truly can't say enough good things about this dealership. My first experience buying a car at another dealership was horrible and left an awful taste in my mouth. However, Blasius South was completely different. Jay, Dejon, and Ross made the process painless. They always had a smile, went above and beyond to help, and were extremely open and transparent! I didn't think I would ever have a good experience buying a car, let alone a GREAT experience. I am truly thankful and will continue recommending them to friends and family! 10/10.
A really hard fine - Ive been looking
This vehicle had everything I wanted, but one draw back it had been used to pull a 5th wheel so there were wholes in the bed.
