I been dealing with this company for a while now.
I been dealing with this company for a while now. I always deal with one of the Service staff " Curtis", he is very Professional , Great Customer Service, always Polite and make you feel Welcome. I never left unhappy with the work he does on my car. He is a great guy and if you're reading this and owns a Mitsubishi vehicle when you need it serviced ask for " Curtis". I'm greatful for all that you do ! Thanks, Tami Williams
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.

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!

We've always had perfect service!
We've always had perfect service! The service staff checked the car first, then asked us about any new concerns or any issues, and discussed. Waiting time wasn't long at all, we've gotten Uber credit to go for a quick lunch, then the car is ready, nice job done!
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.

First-class retailer!
First-class retailer! I was treated with the utmost respect and professionalism by the staff and my product specialist, Christopher, was an expert in the product, extremely professional and very engaging. The whole process was smooth, (very) low-pressure and absolutely hassle-free. Even though I knew what I was looking for, I had the feeling that they would have spent the entire day with me if I needed it. The entire experience made the decision to purchase a vehicle from them a "proverbial" no-brainer. This is the complete opposite of the "infamous" car dealer experience! I cannot recommend the sales experience at Audi Minneapolis highy enough.

We went on the evening of June 24, 2025 to look at a vehicle on the lot, and we ended up purchasing a 2022 Hyundai Palisade. Our sales rep, Austyn Long, was phenomenal. We never once felt pushed or forced on anything. He was great to work with. What won me over was my wife was backtracking as this was a very large purchase, and not once did he try to push the sale. He gave a few words of wisdom and backed off. As long as he stays employed there, he will probably have customers for life.

I recently purchased a 2023 Mercedes-Benz GLS from
I recently purchased a 2023 Mercedes-Benz GLS from Exclusive Auto House, and the entire experience was absolutely outstanding from start to finish. The team was professional, transparent, and genuinely focused on making sure I was comfortable and satisfied at every step. The vehicle was exactly as described—immaculate condition, well maintained, and priced fairly. There was no pressure, no hidden surprises, and no last-minute changes, which I truly appreciated. They took the time to answer all my questions, explained everything clearly, and made the buying process smooth and stress-free. What really sets Exclusive Auto House apart is their honesty and customer service. You can tell they take pride in their inventory and value long-term customer relationships, not just quick sales. If you’re looking for a high-quality luxury vehicle and a dealership you can trust, I highly recommend Exclusive Auto House. I couldn’t be happier with my GLS and will definitely be returning for future purchases.

I would recommend to my friends
I have good experience with this dealership. Pro and cons: Pro: excellent customer service. Thank you Valerie Naval. She helped me and explained everything I asked her. Cons: Car needs to be prep for sale, deep cleaning or at least check it out for anything leftover from previous owner. But Valerie offer me reimbursement for detailing my car. Most of all if you don't like your car for any reason return policy excellent with out any hidden fees, check with your salesperson for details. I would recommend Carmax to my friends .

My salesman was so professional and honest .
My salesman was so professional and honest .he let me know what he can do for to get a car for my daughter. I like his honesty and did just what he say what they could . his name was Travonte Moore. overall the staff was great and professional. we was not there several hours like it usually take . the manager and the finance person was also great . I would recommend them . they were professional and they didn’t give you false promises that they couldn’t keep. That was a plus for me. I would give them a 5 star .and I would like to say I thank them for the great job and experience with them.
