Silver as usual is the safe colour, black and red to look sporty (I prefer the former), and the brown does indeed look elegant and nice.

Don't worry about the problems, most of them can be fixed. For my case, the infamous metal creaking when making a turn was no longer there after driving it for some times.

All this color is subjective as different people will like different colors. For me, white is nice color, followed by silver. But white is solid and not metallic, so difficult to maintain the color. More care is needed to keep the white in tip top condition. With time, the white may lose its shine and turn yellowish. Having said that, other metallic colors will also lose its shine, but the effects may not be as obvious as solid white.

Silver is evergreen and a care-free color. Easy to maintain. If dirty, just use water is enough. Silver is also nice to me.

All other colors - red, black, gold, blue, are an acquired taste. Either you like it or hate it.

For me, the white looks best(disregarding disadvantages), followed by silver.
