Hey,
just got photoshop a couple of days ago and thort i'd give it a shot. All i have done with this pic is add chromes, lowered and removed the door handle and mazda badge.

Quick question: is there any way of making the lines neater when selecting using the Lasso Tool (L) because i've got a bit of an unstedy hand.

that looks great for a first chop, the wheels suit it well

Thanks Sly,
stuffed up a bit on the lower front wheel arch but pritty happy with it.
you don't know how to make the lines neater when selecting using the Lasso Tool (L) do you? because that's why it happen.

zoom in as most appropriately as possible aand select the outer most edge of the pixel to get it clean

dude use the polygonal tool
