2021 GMC Sierra 3500 Denali review

Truck is a Solid vehicle overall.

Has a really Big feel to it. I currently use mine to pull gooseneck trailer. I haven't had a load yet that I couldn't pull. The downsides to this truck is to me I feel it could get better fuel mileage. Also I had trouble with #4 injector...dealership replaced it. Now my AC doesn't work all the time. Although it sounds like it's blowing it isn't.

Bellingham Nissan review

We couldn’t be happier with our experience at Bellingham

We couldn’t be happier with our experience at Bellingham Nissan! We drove three hours to purchase our brand-new 2025 Nissan Frontier Pro-4X, and it was absolutely worth it. Chanel and Forest provided outstanding service from start to finish—quickly responding to all our questions via the website chat and text, helping us lock in the pricing we wanted, and making sure everything was seamless when we arrived. In person, they were just as fantastic! Over two days, we went on multiple test drives, asked tons of questions, and never once felt rushed or like we were a bother. Their patience, knowledge, and genuine helpfulness made the entire process enjoyable. We left with our new truck feeling excited and completely confident in our purchase. We’ll definitely be stopping by to say hi when we’re in Bellingham again! If you're looking for a stress-free, friendly, and helpful car-buying experience, we 100% recommend reaching out to Chanel, Forest, and the team at Bellingham Nissan!

I had made the mistake of scheduling a service

I had made the mistake of scheduling a service appointment at the Salisbury dealership but my appointment was at the Lexington dealership what a blessing it was they waited on me which they didn’t have to so glad they did they saw something the needed attention and took care of it I could go on and on but I want just saying they treated me better than I expected I will drive further to go there even if the other ones are closer

Kevin Smith/Robbie Peters some of the two best if not the best car salesmen, very professional and very curdious, very helpful car salesmen that I have ever had experience with. If your looking to buy a car or anything contact these professionals that truly have your best interest at heart. I applied for credit on a Wednesday and was in a truck by Friday There was no bull or any run around, straight to the point and professional. So look no further when you contact them. Will recommend to everyone to contact them. - R. Wey

Dwayne Lane's Chrysler Dodge Jeep Ram review

I had a absolute pleasure working with Tuan while buying

I had a absolute pleasure working with Tuan while buying a new(used) car in mid-November. He is such a down to earth guy; willing to work with me on my wants and wishes. He helped ease all the anxiety going in and was so personable. We talked and hung out during the waiting process on the paperwork, he was so understanding; helped me set up the radio; got the car all washed up! I highly recommend going in and asking to work with him! He won't disappoint you! Kyle which is a manger I believe; he was very nice also and got me to the price I wanted. Darcee is the finance manager. She is great; we had to go back and forth with paper wok due to some stuff. Which I'm sure was annoying; but she was always professional about it and kind! Overall the whole experience was amazing and it all started with Tuan and being such a kind and understanding gentlemen!
