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 had the best experience at exclusive Autohaus bought a BMW 4 series from Exclusive Autohaus. It’s been six months since I bought the car no problems at all. Financing was really easy. Got the best interest rate. I am definitely going back in future to purchase another car. I did recommend the dealership to my father and he also bought a car from here.
Love this car
This is an S5 convertible and it is a blast to drive. Plenty of power, great interior and is great with the top down. I love Audi's and enjoy driving them.

High Line Auto Sales is hands down the best used vehicle dealership in the area. Their expertise and care really reflect when it comes to the vehicle they sell. I never hesitate to recommend them to an acquaintance, friend, or family member because I know they only sell amazing quality vehicles.

My red S5 convertible was purchased from New Country dealer in Connecticut . It was purchased when I was 70. Everyday when I drive me car I feel 20 years younger! What fun‼️

I found a vehicle at Nexton on Carguru.
I found a vehicle at Nexton on Carguru. Gytis was the salesman that I worked with through the entire process. Gytis was professional, responsive, accessible, patient, and accommodating to my request as I examined the vehicle. When I decided to purchase the vehicle the process went smoothly and quickly. The vehicle was transported and the driver contacted me and informed me on delivery time. When the vehicle was delivered it was all that it was sold to be. I wanted to take time and submit this review because I understand the desire that a customer has to deal with a reputable dealership. Big thanks to Nexton Motors.
