1971 Twister

Sorry to resurrect this older thread, but I am looking at a 71 Twister, with a slant. seems mostly original, but I don't understand the trim on the sides, was that an option? Also the wheel covers? Does $6000 seem sorta high? I do love the Slant. Thanks for your help guys.

Should have A51 on the trim tag. The mirror looks like it is correct. Should have Rallye rims and a shark tooth grille.
