<human>: Give me the gist of the text in a nutshell

So I was pulling out of my garage not realizing that my grandfather was parked in our driveway. I looked beind and to my left to avoid the tree at the edge of our funky curved driveway swung the car back to the right and heard a thud. It was the sound of me hitting my rear panel with his bumper. I get out a look there's a dent and some paint transfer. 

I go to the auto body shop and they tell me they're going to have to replace my cracked bumper and the entire rear quarter panel because of where the dent is located. I have a pretty nice and flashy car with all kinds of curves so just popping it out wouldn't look the right, especially because it's black.
<bot>: I hit a truck I didn't know was there and caused a ton of damage to my car by the way it hit.
