A friend and member here who I purchased a lot from about 5/6 yrs ago had a rule of thumb for xmetals, I was skeptical because I thought some models were not worth it, but he said xmetals $200 and under, intact, just buy it!
Also @GRFMotorsports I think mentioned before he had a habit of keeping $100 bills handy so if he saw a valuable pair he would offer people cash for their glasses on the spot hoping the person just never really thought of selling 10-year-old glasses off their face.
I am glad to report that these tactics have paid off pretty well!
The chances of me even seeing someone with a x-metal frame is like seeing a unicorn. Other than a couple forum members I’ve met in the last 2 years, I’ve only ever seen 2 other people in the wild wearing X-metals. Even back in the early 2000’s. Any Oakley’s I see on faces are usually Holobrook or Gascans. -I wonder what the Geographical location of most X-metal wearers are.
