Highly Recommend!!!
Marvin is the salesman at Lupient who helped me buy my Kia Optima which I was originally leasing. I observed his low key but authentic personality which inspired my trust and made a mental note to request him when I was ready to lease a newer car. Marvin did not disappoint when I returned to Lupient recently to choose a new car to lease. He was able to order me a new Kia Forte with all the features I wanted and more. He explained (with much patience)all the features on the car and how and when to use them. I drove away with confidence that if I needed further tutorials or had any other questions I could call him. I also worked with Don who helped complete the leasing process. He was friendly, informative and comfortable . My experience was extremely positive because of the competent, knowledgeable, patient and respectful treatment I was given in leasing a vehicle I really enjoy driving. Of course, I highly recommend Lupient to anyone wanting to lease or purchase a car. Sincerely, Marsha L.

Just bought a Kia Carnival from Hunter Losch at Ewald's
Just bought a Kia Carnival from Hunter Losch at Ewald's Kia Oconomowoc. He was friendly, ki d, knowledgeable and patient but never pushy. I suggest asking for Hunter for your next purchase and it doesn't have to be a Kia. He can sell anything! Thanks Hunter!

These folks were great communicators.
These folks were great communicators. Rather than focusing on setting up calls, they promptly responded to emails and answered questions in full. They also did a great job of telling me about details on the cars when I went to see it, and explaining plug-in hybrids. When it came to the buying stage, the pricing was clear and exactly what it was online. There weren’t any surprise bonus fees.

Great Buying Experience
I would recommend Lupient Kia and Marvin Cameron to anyone I know. Best buying experience I have ever had. It was a very transparent process with no hidden cost. Taking ownership of the vehicle was very smooth and Marvin gave me sufficient time to go over the options and how they work.

An amazing experience!
An amazing experience! Once arrived I was greeted and given a beverage of choice. Then since a majority of technical information was completed via online portals, was able to sit down and do “paperwork” for less than an hour. For one this made the part I dread the absolute most, an absolute breeze. In addition, I absolutely loved how there wasn’t any pressure to make the purchase or not. It was as if I was buying a car from family! I highly recommend this dealership and will be going here moving forward for future cars!

The staff at Rosen Kia were excellent.
The staff at Rosen Kia were excellent. Sherri who was my initial contact was very responsive to my texts and not at all pushy. Nate, our salesman was enthusiastic and polite. The sales manager was transparent about pricing. It was a good experience. And we are delighted with our purchase.
