B9.5 S4 Solid car
Love this car. Had it for 3 years now. I would recommend getting a after market intake and intercooler.. stock is was to small.. they put in a a4 intercooler to s4 which cause some issues if you live in a hot state like I do.

I worked with Jimmy to buy my new car and he is the best! He is a fun person to work with and gave the total opposite experience then the people that I worked with at the Honda store in Myrtle Beach who were rude and would not give me their price on the car I wanted until I filled out a credit application.

Great dealership!
Great dealership! Great prices. Jaren rocks!!! I drove from PA to Audi Mentor, OH to purchase my Audi because there wasn't another dealership that could compare with regard to price and quality. Everyone was so nice there and Jaren, my sales person, I would recommend to everyone!! Still a rivalry though between PA and OH! GO STEELERS!!!

Car was nice with exception of the high price and rusty rotors. It was just previously washed before seeing it. Made it hard to see if there were any flaws. It is about $10-12,000 more than it's worth.

Went in for a brake fluid change and annual service and had a great experience! Ryan W. was incredibly kind and helpful. Great at explaining things and making sure I was aware of all of my options. They even shuttled us to a store nearby while I waited for my car. I will absolutely continue to come back here, as will the rest of my family!
