10 stars! Honest and outstanding experience thanks to a great culture from start to finish - thank you for making it enjoyable! Khaled took care of my dad’s forever truck purchase with me while also getting my husband and brother keys to test drive their next purchase. From coffee, filtered water and even used Faith’s charger to keep the phone charging to call the insurance company. The Team was caring, helpful and friendly so we highly recommend!

Joe Rossetti is the Best in the Business! I can't say enough good things about Joe Rossetti at Generation GMC. Hands down, the best car salesmen we have ever worked with. From the moment we walked in, Joe made the entire process smooth, honest, and completely stress-free. He knows his stuff, listened to what we needed, and found us the perfect vehicle without any of the usual intense sales pressure. What really stood out was Joe’s integrity and professionalism—he genuinely cares about his customers and wanted to see us happy, not just make a sale. He was responsive, very respectful, and went out of his way to make sure every detail was taken care of. The entire team at Generation was a pleasure. If you’re looking for someone you can trust and actually enjoy buying a car from, go see Joe Rossetti at Generation GMC. He’s the real deal.

We had an excellent experience working with Chris Oliveto at Generation Buick GMC! From the moment we arrived, Chris was kind, patient, and never pushy. He took the time to really understand what we were looking for and went above and beyond to help us find the perfect car — and he did! What truly stood out was how wonderful he was with our kids. He made them feel comfortable and welcomed, which made the whole experience stress-free for our family. Chris is a genuinely great guy — professional, friendly, and committed to making sure his customers are happy. We couldn’t be more grateful. Highly recommend working with Chris!

We had a great experience here with Lawrence Atkins! He helped us get through the process of buying a new truck very smoothly. He was even amazing with my kids, who were getting bored. He also has been super helpful since the sale with any service questions. Highly recommend the dealer and Lawrence. As you can see all my boys love the new truck haha.
