Actually his conversion to white has been done very nicely.
I tried myself the other day and it really isnt just ctrl+u..not even just brightness as certain parts of the car will be too bright etc.
So nice job so far.
I'd place the wheels more outwards but you will need a nice tire donor, try taking it from the rim donor you've got.
i tried aswell brian, the white is very well done, and i can even see a bit of brushed parts, cause the white conversion just by playing around with brightness makes a lot of quality loss, keep it up, i still think the wheels need some twiking around
