Overall Good Experience
Purchased a used Audi recently and was very happy with the sales person, Sabina. She was patient, knowledgeable, and communicated very well (responsive). Ended up financing because we were out-of-state buyers. The finance manager was fantastic and worked quickly. She was also very knowledgeable and helpful. Here’s why I only rated 4 stars - there was some sketchy deferred maintenance that was not addressed prior to offering the car for sale. Notably mismatched front tires and 4mm rear brake pads. The dealers own tech inspection sheets noted the need for immediate attention to the rear brakes, but they were not replaced. Mismatched tires, in my opinion, are also a safety issue. I can only imagine these issues were not addressed to maximize profit and that’s okay as long as the car is priced right. And it was, BUT I can’t imagine a less than 2% change in price would have stopped a sale. Safety is paramount.
Love the car only had a coolant pump issue but ever since
Love the car only had a coolant pump issue but ever since it's been smooth sailing. The car is gorgeous and incredibly comfortable with beautifully designed interiors. I've drive both the Mercedes c43 Amg and the bmw 340i which I think are this car's competition and I'd still have this as my overall pic.

What a convenient way to buy a car!
What a convenient way to buy a car! I love the car, it is exactly what I wanted and not being local, it doesn't have the salt rust that cars here have. Extremely smooth process. No pressure, yet very responsive. Much appreciated.
STUNNING MACHINE S5 Cabriolet
I can write an entire diatribe about this car but I'll keep it simple! If you are looking for a luxury, convertible, look no further than the S5 cabriolet. I looked at the C43, M440i, this car, IMO, is the BEST value for the money! It is an absolute beast in the performance department, the options that come with this car for the price are unmatched and of course every single detail is perfectly executed!

I haven’t purchased here, but I’ve been a prospect and they are well priced and very transparent with the vehicle history. They’re also prompt with follow up. The person who posted the fact that they are Ukraine owned has zero impact on them as a business. In fact, the same person posted twice just to damage the ratings. There’s always a dingdong out there.
