I've owned a couple of the standard Addcos with white top and they last about 2-3 years in the hot So Cal sun. I'm gonna look at Goldline when I get my next cover. Looks like a better cover. All the reviews I read have been positive. I have kind of a love/hate relationship with the covers but they sure do keep the TT nice and clean.
