Who Helped Me:Joe K
Joe K made this the easiest purchase I have made in many years! No games!! No time wasting!! He was kind, and answered all of may questions. When I accidentally left something behind at the dealership, he offered to meet up with me after work so I did not have to take the 45 minute ride back to the store. Lou the finance manager was just as honest.....I will do business again with O'neil and Joe!!!!

Who Helped Me:Ray Pelletier
In January of 2014, I purchased a Certified Pre-Owned 2011 Buick Enclave from Sullivan O’Neill’s in Avon, CT. I scheduled an appointment on September 9, 2014 to have the air conditioning checked and to have a safety recall issue taken care of. I had four months left on the warranty. The air conditioning was making a whooshing noise and was not cooling well. I got a call from Ray Pelletier, the service manager, a while after I dropped off the car. He said that a mouse had built a nest inside the AC unit. He further stated that this would not be covered under warranty, that they would have to take the whole unit apart to get at it, and that it would cost well over $1000 to do this. They did not have time to do it that day. When I started to use the air conditioning this season, it again made a whooshing sound and did not cool well. I brought it to Gallagher Buick in New Britain. They found that I had a bad actuator, which would have been covered under the warranty. They found no evidence of a mouse nest in the system. This cost me $549.47. I complained to GMC, who contacted O'Neills. They first tried to say that I refused the diagnostic on it. This was ridiculous. I made the appointment specifically to have the problem fixed. Then they said they wouldn't cover it because the warranty had expired by the time I brought it to the other dealer. My error was in trusting the service manager when he told me it wouldn't be covered by the warranty. If I had not, I would have brought it to another dealer over the winter months. I had no reason to do so until the spring because I thought it would not be covered. I am extremely disappointed with Sullivan's customer service and would never use them again.

Who Helped Me:JIm Porter, Joe, Lou
Couldn't be happier with the experience of leasing my 2015 Buick Regal. he entire staff at O'Neill's was helpful and very knowledgeable. Jim Porter was excellent. He listened to what I wanted, advised me to the best options available and although the exact vehicle I wanted was not on their lot, they went out of their way to locate and get my new Regal for me. I couldn't be happier or more pleased with the entire experience from the time I entered the showroom and Jim greeted me to the time I drove off in my new car. Will definitely recommend O'Neill's and especially Jim Porter to everyone I know.
