IMO if i was in your position I would definitely go with grey...i would go metallic grey but either way. I would say grey because i see too many white and black integras, because those colors came stock and they are very common. You don't see grey integras almost ever, and its a great color for tegs.
Coming from someone who had their teg painted, go with something unique. You get bored of looking at it eventually with just a regular color. I went with Milano Red just cause I didn't want my bay to be different and I didn't want to pull the motor at the time
^ Eso! (this en espanol gotta brush up on that school starts soon ) anyways I feel bad for the kid having to read these things and imagining what couldve been, and now he has to start over
