Northshore Rainbow dealership excelled in all aspects. My salesman A.J.Smith was very knowledgeable and answered all of my questions. I felt very comfortable and trusted his advice. I also met Matt and enjoyed meeting him. I look forward to dealing with Rainbow in the future. They seem to be a dealership that I can trust.

I purchased my Buick Envision from Sean and it was financed by Matt Smith. This is my second car purchase from Rainbow. I really appreciate that my needs were recognized and responded to in a positive manner. I really wanted to downsize from my GMC Acadia and into a smaller vehicle. The Buick absolutely fits my needs. I wouldn't hesitate to recommend Rainbow to my friends. As far as car dealing goes, Rainbow is a pleasant experience. Thanks Sean and Matt.
