Purchased a new vehicle Monday, 5 October 2015, about 12:30. They had to trade to get it from another dealer. We never received the vehicle until after 1:00 on Friday, 9 October. Then while trying to set up the OnStar it required: Tech Level 2 support, a software update, and now we're told a new part. Everyone was EXTREMELY nice and friendly until I didn't do what they wanted (like purchase extended warranty) and then became angry/disrespectful. The General Manager called me from the gym while working out, breathing hard, and clanking equipment to ensure me I would get good customer service. Every employee that I had interactions with told me something that was not true. We are taking the brand new Buick to another dealer tomorrow for repairs since we can't trust Koons. My personal opinion: I would not recommend Joyce Koons Buick to anyone.
