Very Quick and smooth process. Sale agent victor was really nice. Would definitely do business with them again! Thank you again!

Just trade in my 2015 GMC Denali with 140000 miles on it and still holding strong at trade in best SUV I ever had upgraded to the new 2021 Denali and boy do I love this SUV from comfort to outside design just an amazing new well designed SUV.

We had a great time with Matt Kass, he didnt seem pushy he took his time let us make a couple choices on the car then gave us the right car at the right price Im so glad we had the right salesman to work with Will send all my family and to him

I own a 2023 Sierra 1500 Elevation equipped with the 2.7L TurboMax, and it’s been outstanding. It currently has 23,000 flawless miles. I’ll admit, I was skeptical of the 2.7 at first, but I jumped in feet-first and have never looked back. Living in Colorado, I regularly tow a 5,000-pound travel trailer through the Rockies with zero performance issues. The truck pulls confidently, handles grades with ease, and still delivers impressive fuel economy—23–24 mpg on the highway and about 18 mpg in town. I couldn’t be happier with this setup. If there is a negative to mention, that would be that after three years of ownership, the black wheels havent grown on me, and Im beginning to hate em. :) Lastly, the mpg while towing drops to 9mpg which is similar to that of a V8. All said, its been a great truck. :)

I recently had a wonderful experience at Mazda 112. My sales person Bonnie was amazing. Bonnie was extremely knowledgeable, friendly, professional and helpful. She answered all my questions, listened to what I needed and wanted, and put me in the perfect vehicle!

Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.

We had a wonderful experience with CJ and Brayan. They were kind, patient and answered all our questions. They helped us find the right car for our daughter. We were more than pleased and will be back for another car in the near future. If you need people you can trust, come here.

Purchased new in October 2024. Total miles driven 9,276. Just completed a 4,734.2 mile trip through 9 states. Just a pleasure to drive. My wife and I were on the road 16 days, with only 8 driving days, longest day was 674 miles. Average driving speed was about 72+ miles per hour. Seat comfort was amazing, no discomfort, great considering having 4 back surgeries. Very solid on the road with little or no driving fatigue. Performance was great. Of the total miles, about 500 were in town driving and 300 miles was in 4x4 in a snow storm coming across Northern Texas in April. Average MPG was 26.4 with my best 500mile drive at 33mpg. The diesel engine is very quiet requiring me to check the tach sometimes to be sure I had pressed the off button. Very quiet on the road as well. This is my first diesel and I would highly recommend it. Plenty of power, great fuel economy, quiet and very responsive when you need that quick acceleration. amazingly nimble for a big SUV. The adaptive cruise works great. My previous GMC was a 2009, 6.2L V8 Yukon XL. I drove that one 140K miles over 14 years with nothing but routine maintenance, a great vehicle as well. Very happy with this 2024

My service advisor Andrew was very helpful and he explained to me about a repair that was covered under my warranty agreement but suggested I follow up with the original dealership to verify specifics about the type of warranty I have.

Stong engine and smooth! Highly recommend for familys or someone who likes a smooth truck. Purchased new and have had zero issues since then. Love it!

DeJon Was an awesome salesman I highly recommend blasius as it is always a pleasant experience I have purchased my last 3 vehicles with them and have family that has bought vehicles from them. I love how friendly and personable DeJon was and made the experience very smooth. The finance manager Veronica is awesome. Thank you for my Tesla model Y

My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

Very very happy with the whole experience. Everyone was very professional, quick courteous. Everything was taken care of in a timely fashion probably one of my best experiences ever at a car dealership recommend it highly.

I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

Peter was the best. I have over 50 automobile purchases in my life time. And this was the easiest and best one yet. Thanks again

I bought a 2019 GMC Sierra Elevation. I traded in a FULLY loaded 2015 Sierra SLT, that I was really sad to see go, but the Elevation really sold me on styling and ride quality. I lost a couple high end bells and whistles, but the overall performance and look of the truck make up for it big time!

Best used car purchase experience I have ever dealt with. They were patient, helpful and did everything to make sure I was comfortable with my purchase! Highly recommend Dan and team

Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

Great service from Zach. Very knowledgeable and thorough. Will definitely recommend him and Generation Buick GMC to my friends and family.

Let me start by saying I have the AT4 model with the Duramax 3.0L diesel. I had a 2024 Elevation with the 5.3L V-8 that I bought to pull my 22’ camper. While the Elevation pulled my camper fine it drank the gas like it was on a binge. And with a 26 gallon gas tank it seemed I was filling up every couple of hours. After one trip to Nova Scotia I knew something had to change. I pulled my camper out west to Yellowstone and back through Arizona. It pulled like a champ and fillups were a lot more manageable. Even driving the speed limit out west I still got four to five mpg better than with the gasser. I liked the Elevation but I love the AT4. Way nicer ride and great handling. I get 30 per gallon of diesel on the highway if I drive the speed limit but I got it to tow with. I added a Titian replacement fuel tank so I have 43 gallons instead of the 26 it came with.

Wow what a complete difference in professional service from Generation GMC in Sayville compared from King O'Rourke in Smithtown. Service department is amazing. They send you a video from the mechanic going over all the concerns that you have any what they found. I was constantly being told my oul leak was a seel. Thanks to Generation GMC they took the time to find the real cause and it's going to take a week to fix. Thank God had the issues at King O'Rourke otherwise I wouldn't have found an amazing dealership. Especially Thanks to Maria for keeping me updated.

Okay but what is the best way you can do this for with a good price and a nice price for a decent price like this one for like two or five years and a good price for a really good quality one of the ones that I got from the

See Will for the best sales service. He gets to the point and he’s super friendly!

Excellent experience buying a 2020 Ford Expedition Limited MAX SUV because my salesperson, Carmine Randello was honest and helpful rather than pushy. Carmine had a way of making me want the car without trying to make me want it.

This truck is great if your not trying to haul 10k lbs. For every day use it's great on gas and I fit everything I need in the bed.

I bought this truck new 1/22. Have put over 100K miles in 2-½ years. No problems. Have 5.3L and 10-speed. Very reliable. Nothing has gone wrong. I feel the seat cushions are too short for someone over 6’.

Our experience was very smooth, the gentlemen at northbay Cadillac was very nice, understanding, was treated very well..Chris, John, Petar and David..John took time to show us step by step the features in our GMC Sierra Denali, they were very patient and they answered all of our questions..they were an A+.. great job guys..

I love my car. I love the way it handles, and the confidence I have in it when I’m on the road. The room in it is fantastic. All the room I need for when we travel.

My review is about Paul Whaley; i have only good things to say about him. Paul is a young man, very respectful, professional, attentive. He is very patience young man and always in contact with me without put pressure on me .Thanks Paul for all your efforts to close this deal, and I hope we do it.

Ordered a 2023 GMC Yukon XL Denali Diesel 4 wheel drive in March of 2023. Took GM 5 months to pick up the order even though I adjusted a few minor options that were on constraint to have the order picked up (these were items I could purchase the parts and have the dealer install such as illuminated GMC emblem, Denali door sills, illuminated GMC cargo sill, cross rails for roof carrier). I wanted the diesel for the mileage and longevity. I am very satisfied with everything with the vehicle so far. Ordered the 20 inch rims/tires for a better ride. The ride quality is remarkable, so smooth. I drive a combination city/rural each day and I average 25 or more MPG. I have 9000 miles on it so far, and not one single issue with it. It is smooth, quiet, and and packed with technology. Goes through the snow with no problem. I have had 7 Suburbans, Yukon XL's and Escalades and in the past, full size Cadillac Broughams, and this is the best riding vehicle out of all of them. I am very satisfied. The only issue is the price has gone through the roof to purchase new. The Suburban and Yukon XL used to be more affordable new. My previous 2015 GMC Yukon XL Denali has an engine issue (camshaft issue even though the oil was changed at the dealer every 3K miles) at 165K miles and I had to trade it in quickly, so the dealer took it on trade when I ordered the 2023, and they wholesaled it. I was not going to buy another one with the 6.2 liter engine again.I really hope the diesel will go for many miles and years, and so far this vehicle has had no problems what so ever. Very glad I made the decision to try it again with the diesel engine this time. If the diesel was not available I would not have bought another GM full size SUV. Classic Painesville Ohio is the best to work with for sales, service and parts. They kept me posted throughout the purchase process and were very fair with the amount for the trade in and purchase price for the new vehicle.

I recently had my car serviced at Napoli Kia in Milford. Courtney my service advisor really made the experience seamless and helped me navigate replacing a tire. Everytime I need service it's has been a pleasant experience.

READ PLEASE I love my Terrain. DO NOT get the 1.5 L. My engine has barely made it over 100,000 I have had $6k of repairs in less than a year. Things keep going wrong now. I had NO issues before. Catalytic converter went out 75-85k miles. My turbo was just replaced. Just beware of this type of engine… every mechanic that worked on it shared this is not uncommon for this type. I would definitely get another terrain but not the 1.5!
