The vinyl roof may very well be something that was added after the fact (maybe by the dealer or an individual), I can't recall seeing one that stopped at the halfway point of the roof. The graphics could be the same case, but I think I have seen something like that on a 510. If the graphics are factory they were probably an accessory and have long since been discontinued. The paint code sticker is usually located on the core support to the left of the radiator (from standing in front of the car), if it is still there and not faded you can look in the wiki on this site to find what the color is called.
Looks like a good straight car! Any other plans other than paint?
