Napleton Buick Service Department
Kept me informed of status of repair so I could decide if I wanted to wait for the repair. Customer waiting area always clean and comfortable. If the repair extends longer than I can wait, will provide.a ride home which is a great service. Always explains what is needed and what can wait until next service date so I can be prepared for future maintenance. This helps me keep my car in great shape and prevents major issues.

We just had a very positive and smooth interaction and
We just had a very positive and smooth interaction and used car purchase with Castle Chevrolet. We were shopping for a replacement Chevy Trax for my 86 year old mother in law and I found one on Castle's web site that was a perfect fit for her. I phoned the dealer to let them know we would be coming in. We were met by Jeff Vicari who handles our entire transaction and sale in a professional, courteous and respectful manner. My typical opinion of dealing with buying a car normally isn't very favorable but this experience was awesome. We did have a minor issue with the loan paperwork but it was our fault, I contacted Jerome Witt ( Sales Manager) who said he would fix the problem - low and behold, it was fixed within the hour. My thanks to both of these guys for making the transaction positive!
