^this.If they're still doing the Ingot Silver Metallic that's a good choice. It doesn't show dirt nearly as well as most other colors.
That's true. If my car gets scratched for any reason it might be hard to find someone to match that paint exactly. That would be my only real concern.Well you should get a color you like.
Some considerations can be:
For lots of sun: White is best. If you live in Southern California, or Florida, then a White car really can make a big difference on the interior being cooler.. far cooler than any darker color.
If you drive fast: a car which is just like all the other cars.. Then any grey scale car. No red, no bright color..
If you DO want to stand out. Then a red car. Or if buying a ST, the Tangerine Scream. Plus can you find YOUR car in a shopping mall lot? If your car is the same color as 60% of the rest?
For Winter with snow climate: black looks like Hell when dirty, so does White. Yellow the worst of all. If you really keep your car super clean, even in Winter, those colors will stand out when all the other cars are full of dirt.
For car repairs, plain colors are much better than tricoat metallic for repainting.
Get you some Rokblokz. Makes a world of difference. My car hasn't been washed in over a week and it only started to look dirty today. No five o'clock dirt shadow on the bottom quarter panels two days after you spent the time and money cleaning it.^this.
My car never looks clean (up close) for more than 24 hours.  If you want the car to look clean all of the time, avoid dark colors.
This^^^^ all about choice's as well as used car colors,,,,I've never bought a new car, and barring winning the lottery, it's fairly unlikely I ever will.
That said, if I DID buy new, you can bet I'd say phooey on practicality and buy the color that makes my heart pitter pat
