Buying out at end of lease

I leased a 24 Land, loved it so much drove it 20K over the limit :). Planning on purchasing as giving back would cost me and current lease/finance deals aren’t hitting. Even looked at the telluride but feels like a downgrade tbh.

Question is anyone buy out their EV9 at the end of the lease and how did it go? Do you buy it out from the dealer or Kia directly? What are current rates looking like? I’m seeing anywhere from 6-9%

Loving the ride more and more everyday and looking forward to keep in the car for years!
