genuine rs2000?

[groulder]

going to look at an rs2000 on the weekend.
it's a 1980 2 door model.
i've compared it with pics of other rs2000's and noticed some differences i wanted to query.

it doesn't have chrome gutters which i've read did exist on rs2000's--it's gutters are black.
other rs2000's i've seen have a faded looking fairly wide strip the length of the car, close to the sills. this one has pin stripping the length of the car, higher up.

finally, did they all come with quarter vent front door windows?
