I spent more than $2k this spring buying 10 bikes. I've sold 1 and a wheelset from those purchases as well as 8 bikes from my collection so far this summer for almost $3k.
It's amazing that my wife tells me to buy most of these. After buying/selling bikes for so many years, she recognizes that I'm able to keep it a fairly "cash positive" hobby and it keeps me out of her hair.
I'm a lucky guy.
