Happy Steve
I used to lease a Mercedes C300, but the Audi A4 has better tech, is easier to use and a comparable ride. I am a happy customer!

If I could give more stars than 5, I definitely would!
If I could give more stars than 5, I definitely would! Lila Bubier, Mark Deal, trade checker and Kia Finance went above and beyond to get me out of my negative equity from my Hyundai Ioniq 5. I am so grateful to have a new 2025 Kia Sorento Plug-In Hybrid. I had originally went in February, but did not come away with a deal. Lila has consistently reached out to me asking if I was interested and provided many different options to get me at the price point that I wanted. It was not easy, but we made it to the end goal. My growing family and I are so grateful to have this amazing team working at Kia and I hope to continue this new relationship with them at Blasius for years to come! Thank you so much!!!!
Excellent Vehicle
So happy I extended the lease on my previous A4 to wait for the new 2021 A4s to come in. Except car both inside and out. Meticulous attention to detail and the new standard features in the 2021 A4 are incredible.
