Amazing experience!
Amazing experience! Steven Verizzi was wonderful to work with. This is the third time we bought a vehicle from Emmons Autoplex, second time that we worked with Steven Verizzi and we couldn’t be happier, he is absolutely amazing! And their coffee machine is great too.

Immediate response.
Immediate response. Made an appointment to see the vehicle. Unfortunately, it sold before I arrived. However, the salesman did not make me drive over an hour to get there to find out it was gone. He called and texted to save me the trip. Really appreciate his respect of my time.

Great simple oroceds
Rees was my greeter and was an excellent source of information and sales expediter. Rees explained the CarMax process and then Listened to the car features I required. He did searches of car max inventory, searches of manufacturers’ sites for additional info, and requested transfer of a vehicle from another location. There was no pressure to buy (CarMax has a five day return policy). Paperwork was efficient, and I even got help getting both the car I bought and the car I arrived in home. It was my first solo car buying experience so I especially appreciated that I got a car that suited me at a fair price and no hassle
