The Targa should have a black top and flat black roll hoop as per the late 70s/80s model , not the 60s /early 70s style bright aluminum hoop as per this pic, since there is very little chrome on the modern 911 to balance it visually
Having said that, my first 911 was a triple black Targa, chosen because the first gen cabs back in the mid 80s had tops , raised or esp lowered that were ,IMO, not attractive . The 991 cab now has the sleekest top , raised or lowered , of any 911 and I would chose that over even a retro hoop style Targa .
