I have a pair of the vintage Porsche Design glasses. Got them in the 80s.
Back then the plastic frame Carrera ones had just come out and were $42usd. These were $225, and fortune for glasses back then. I went to a local sporting goods store and asked to look at the expensive ones. I asked what they cost and when the sales person said $42, I immediately bought them. They made me look really cool in my 914.
