I purchased the new 2025 Kia K4 EX during late August for my wife to help celebrate our 55th wedding anniversary, and she simply just loves driving the car with all of its modern safety high-tech features, its comfort, and impressive driving performance. I've nicknamed the car "The Batmobile" with its Aurora Black Pearl exterior paint and stylish features that make this car stand out from other sedans that are in the cost-effective $20,000 - $30,000 price range. Plenty of room inside the car, a quiet smooth ride, and adequate acceleration whenever may be needed (e.g., entering onto a highway). The car comes with Kia's standard 5 year, 60,000 mile full warrantee, and 10 year, 100,000 mile powertrain warrantee which is still very generous of KIa.

My experience with Kunes belvidere
This is an update to previous review. I bought the cerma plate protection package but was unhappy with the interior. I took it back and it turned out that nobody even worked on the interior. They did it while I waited. If I hadn't taken it back I would have paid for something I didn't get. The service dept. was a little upset with my mood and attitude, but when they found out no-one had even worked on my interior they were very apologetic and nice about it and thanked me for bringing it to they're attention. I don't like dealers and this is a perfect example of why.
