2003 Yukon Denali Bottom 100% Rusted

[GmcOwner13]

I am 100% disappointed in the condition of my yukon. I am the only owner since 2003 and barely used the car it is only at 68k miles right now all i used it for was to bring kids to school and a few road trips. Recently i was out to get some gas and on my way home the brakes failed while i was going around 40mph. Luckily nobody was hurt but when i brought it to the mechanic and they put it on a lift i noticed the entire bottom of the car was rusted away. I ended up replacing the entire brake system and have made my decision that the Yukon will be my first and last GMC to own. Im looking to sell it asap now. Even my mechanic has never seen a car in this condition before.
