Guess what ....people do things "because they can"....If you had more money than you knew what to do with and those flares were important to you for what ever reason...guess what you would do....Buy them. It's all a matter of perspective, and the more money you have the broader your perspective can be.
For instance.....I just purchased the the 50s collection of Road & Track. I was ready to go big. Why because it was all I needed to complete my R&T collection. It was important to me and I could afford to do so.
Oh ya...it made me feel warm and fuzzy inside.
Saying that, I would never spend so much for flares.,,,Id make my own....lol
