Should the rockers be dark on a 230? (I dare not say grey or black
)
In the boot for the convertible top, the paint looks too shiny and it appears the vinyl has some of that gloss black on it. I believe some of the hardware is painted silver where it should not be (in the same picture).
The battery hold down would be wrong for a 280. Other's will have to confirm or refute it for a 230.
Tail pipes either wrong or installed wrong (sticking out too far).
Interior color look soooo red, almost apears dyed. Also, compare it to the convertible boot vinyl, looks different to me.
Not sure, but gas cap might not be original.
Various hose clamps under the hood are not original.
Does it have headlight notches???
Maybe the Data card is in the glove box? (Like mine was.).
All of this is no big deal, but you asked about originality.
Looks like a really nice car with many really nice things about it.
Enjoy the ride !! I hope you go for it.
