New and used 2025 Kia K4 sedans for sale near Cudahy, WI

We knew where we wanted to get our next KIA from. Marvin and team Lupient were on it and helped us get the car we needed. Thanks guys! We will be back again.

Great car at its entry price. Rented both Honda Civic, Volkswagen Jetta and Kia K4. Drove all for week (7 days). The Kia won hands down. Bought Kia K4 for $23,400 over 3 months and it has better warranty than its competitors. Safety and accessories are part of Kia’s factory standard install compared to up charges from Honda and Volkswagen. Love interactive cruise control and its Saftey features.

Tiara was very helpful and professional. I will recommend to family and friends to talk to her if looking for a new car she definitely went above and beyond

You don't necessarily need an appointment for oil change..service writers all ignored me when first came in..not one of them was with a customer either..terrible customer service!

Service department is second to none! Jermaine is the best! He answered all my questions and got me in and out in record time! A++

We couldn't have had a better experience. Josh was amazing and one of the nicest people you could meet. He went out of his way to make sure everything went smoothly. Everyone was very friendly and helpful.

Excellent experience with Bernardo!! No high pressure sales and great in depth assistance learning all the features of the vehicle. Bernardo and Matt were very upfront and honest listening to my needs and fulfilling my wishes for my next perfect car! Thanks so much!

Faith is so awesome!!! I love Rosen Kia! Buy from Rosen. I like being part of the Rosen family. Great team of sales reps. Great!

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!

We leased a 2021 Kia Seltos thru Dennis Cardinal. This is actually the second time we leased from him. The first vehicle was a Kia Soul. Both were excelent experiences.

Fantastic employee assistance and buying experience. Huge thanks to “LJ” and Dogan for getting me hooked up with an amazing Toyota Camry

Each person I interacted with from the service advisors to the shuttle driver, was friendly, and helpful. It certainly made a stressful experience more enjoyable. I felt like a valued customer the entire time.

Although I ultimately did not buy a car from this dealership, I was thankful for their assistance during my shopping process. My sales associate, Griffin, was extremely helpful - patiently answering my questions and providing me with information that I was looking for. Hopefully we'll be able to cross paths again sometime!

Bought a new Kia Seltos from Boucher Kia, and the sales and management folks with whom we dealth throughout the process were always respectful and as helpful as they could be. Did experience two significant frustrations, neither of which appears to be the fault of the dealership. The first was a 6+ month wait for the Seltos we ordered to be delivered. This kind of delay is on Kia, more than the dealership, so I don't fault them. The second frustration was that the 2WD version of the Seltos we ordered is apparently not something Kia gets a lot of orders for and thus is not something they want to produce very many of. The car Kia produced to fill our order and sent to the dealer was the 4WD version of what we ordered. The dealership apologized and gave us a discount off the higher 4WD price, but again the core problem was with the company. If Kia doesn't want to sell a 2WD version of this Seltos trim, their website should not offer it as an option. That said, so far we really like our new Seltos, and we give the Boucher dealership credit for working with us.

Great customer service and reps were amazing as well. Faith followed up with me after my visit to ensure everything was taken care of and I was happy with the service. I was very happy and after the call I got an award very cool!

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.
