Clement Hyundai review
Had an appointment with a sales consultant.
Had an appointment with a sales consultant. He was very helpful and patient with my questions. I did not purchase from him - it was about the car, not the sales consultant.
2025 Kia K4 EX review
I purchased the new 2025 Kia K4 EX during late August for
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.
