what do you think so far...? only if ur bothered to read?

It's quite good. You really need to put capital letters in the correct places, though.

Like one person suggested, extend your description of adrenaline. Be more specific and really draw the reader into your story.

Here's an edited version of your story, if you'd like it. I haven't changed much - only a few words, the arrangement of sentences, and grammar/punctuation.

Carefully, I walked towards the car, my friends cheering me on. I felt the adrenalin rushing through my body.

'Go John!' they all shouted around me. "Just do it!"

I looked at the car, frozen for a second. It was parked there on its own, reflecting the sun's bright rays. It was a hot, Saturday afternoon, and no one was around. No one around except for my friends, all standing, waiting and watching me, as I stood there, staring at the car. I held the metal bar tightly in my hands, as my palms started to sweat. Quickly without stopping to think, I took swung the metal bar.

CRACK!

Suddenly the alarm went off, blaring into the otherwise silent car park. I jumped, turning quickly and sprinted as fast as my legs would carry me. I just kept running. I didn't know where i was going or why - only that I shouldn't stop, shouldn't turn around.

After what seemed a thousand years, I caught up to my friends. They were all laughing hysterically.

I was shocked. I'd never done anything like that in my life. It felt so exhilarating. I knew it was wrong, yet some part of me wanted to go back and do it all over again.

The streets were darkening and I decided I should go home. I walked myself down the empty streets until i reached my drive way. I wanted hide away in my room and not come out until the next day. I noticed my parents' cars were parked outside, so they must have been home early.

A light caught my eye. It was coming from the dining room window, which was strange. We rarely used that room - only for special occasions. I looked around for other cars around the house. Were we expecting guests?

I opened the door and walked inside.

This story left me wanting to read more, but I also wanted more from your descriptions. What happened to your friends? Did they laugh and run home? Or did you go back and bang up some more cars? Tell us more about your emotions during this scene.

Good luck!

Yeh this story was fine.

Only problem I thought was the repetition of the word 'friend/s'

Use words like comrades, mates, accomplices, etc

Oh and maybe a bit more explanation on the dining room, explain its importance so as to emphasize its mystery, and maybe extend your description on the 'adrenaline rush' that your character is experiencing.

This is just so that it creates more tension and so that we can understand and relate to the character more efficiently.

Very good :)

I liked it! Very interesting - the character of John is very endearing, and this introduction would make me want to read more. Well done! (:
