I think the red one has been repainted. If you look inside the R/R wheel-well you see red paint in there. That shouldn't be the color of the exterior should it? Shouldn't it be black like all the wheel well? I don't know this for sure but it seems like it's been repainted and they didn't do a good job masking off. Then again, like I said, I could be wrong. But I would think a repaint is a good thing as long as it was done in good intention and a decent job of it.
I personally like the black one. Limo's should always be black unless they belong to Elton John or someone like that.
