Same old car dealer tricks
Update, I was quickly contacted by the GM who promised to make good on the car by either getting rid of the smell or take the car back.

Our sales rep at BMW Mckinney was the very capable Mr.
Our sales rep at BMW Mckinney was the very capable Mr. Steven Saroyan. He was nice and professional to deal with. He was very transparent with the way the process works and showed us the best deal we could go with. Car shopping is not something most people enjoy doing. I don’t pretend to speak on behalf of most people, but at least that’s what I think. I want to thank Mr. Saroyan for making the experience not terrible 😄😄. One other note, all the people in the dealership were very pleasant and friendly. We didn’t even make it inside the building before one of the employees greeted us with a smile and said hello. We were asked several times if we were doing OK and if we were being helped. And for those of you who like snack bar, there’s a good one here. It may be a small thing, but I do enjoy a well stocked and complementary snack bar.

Great Service!!!!!
I truly enjoyed my shopping experience yesterday on Friday. October 2, 2015. Mia was very patient, professional, and caring in listening to my needs and concerns. With God's and Mia's help I was able to purchase a 2015 Ford Focus. Thank you again Mia for being an excellent salesperson. I will definitely recommend CarMax to my friends.
