Mercedes problems

This was the story I wrote in class, it might not be great, but no one ever promised you it would be. Here it is:
In a dark and cold room, I awoke to a man pacing back and forth. He was mumbling to himself about how he shouldn’t have done it and how he shouldn’t have over reacted. I then began to wake up more and noticed blood on the bed next to me; I freaked out! I thought I had died! I thought I had been stabbed! What was going on?! I jumped up and realizing I am obviously still alive, but I notice a body covered in blood on the floor next to the bed. It was a woman who we had been talking to the night before. I couldn’t remember how we began talking to her or how we got into this room. Then suddenly I remembered; my friends and I had decided to hang out and this must have been what happened. I can’t remember any of the night! All I can remember is doing shots in the hotel room and then I blacked out. What did I do to get here? Why was my friend covered in blood and a woman dead on the floor? What was I going to do to get out of here? I quickly grabbed my friend and ran out of the house. My Mercedes was sitting in the lot. Why the hell was my $100,000 car here? Did we drive it drunk? As I walked closer to it I began to worry more and more about what we did to it. As soon as I got close enough I saw all the scratches and dents; the hood was also popped for some reason. I guess we tried to do some late night engine work. I hope not, because we probably messed some shit up bad. Anyway, I didn’t care anymore; I would fix the body later. I threw my friend in the car and threw all the beer out; just in time to hear the police sirens. I jumped in the car myself. I tried to hit the start button and the car wouldn’t recognize the key was in the car. Was the key in the car? I had no idea where I could be otherwise; I searched my pockets. When I couldn’t find it I ran back inside to discover the key was on the end table with both my wallet and receipts. I quickly ran outside and jump in the car and drove off before the sirens got to close. I managed to make it down the street and around the corner, but I knew the cops would be looking for me. I began to drive toward my home when I happen to break down on the highway. With both my friend covered in blood and both of us still drug off our asses, a cop pulls up with his lights on to help us because we have broken down. The cop helped us get out car over by keeping traffic back and once he had us to the side I knew he was going to arrest us for DUI, so I decided I had to do something. I would back up into his car and pin him while he was walking around the car. I knew my transmission was out in drive, but I hoped I would still have reverse. So I gassed it and realized my car only had reverse, so I kept going in reverse until I cleared the car and cop and fled backwards. I ended up making it home and ditching the car off a mountain b/c who need such an expensive car anyway, all u do is worry about scratches and dents and how u might mess it up. So I had to explain to my wife where the Mercedes went, and I told her it was just having too many problems and I couldn’t keep it. She’ll never know what really happen that Friday night, but I will always remember those few parts I wasn’t blacked out for.
