Questions about 82-85 Riv Convts

[StylishOne]

Been looking for a good Convert and there are like 8 for sale right now: a few beaters, one very nice but high priced, and a few decent ones. 

 

Is there a most preferred  sought after year? Any desire able options? 

 

Reading the brochures I see only a red or later dark red interiors on later models .  But rtecently discovered 2 odd interiors. One 83 has white contrasting piping on the normal red interior? Looks nice and original..then I found an 84 with the pleated inserts in all white with red bolsters, it too looks original ..and has a maroon convert top! 

The brochures dont mention anything but solid red trim. so can anyone tell me more about these two? Or maybe a dealer ordering book tells more about this if someone has one? 

Curious to learn more.. I also saw a photo of a white with black interior and top.. but that might be a preproduction mock up..
