Lovely job so far Serin, thats pretty much the sort of thing that I would have done.
Keeping the 4 doors works well if you go down the Touring car route
Are you gonna attemp to change the colour ?
Here's a tip for anyone changing the colour on a Dark car.
Don't use the normal Image/Adjustments/Hue, Saturation trick...
Instead use the paint brush after selecting the whole area that needs changing, set the opacity of the brush to somewhere between 25 and 60 depending on how much you wanna change the colour.
Then set the flow to 100% and the Mode, I would set at soft light.
Use a large brush size and wipe over the whole area once without removing your finger from the mouse button.
If it's still not the colour your after then go over it again untill it's a deeper shade..
You all probably know this anyway, it's just that there was a complaint that the colour was a bit dark.

so i thought I would tell you what i do.
