Does it stop? Magic 8 ball says: outlook does not look good. I have been doing the vintage bike and flip for profit thing for only two years now. I just looked at some of my records and I have purchased 99 bikes in that span. I have sold 60 of those, and the rest are hanging around mostly here in the basement shop. My personal collection of bikes is up to 11 (three non-vintage MTB and two slightly newer track bikes). The other 6 are vintage and were the top of the line or close to it in their day. The amount of money I have spent on those combined wouldn't buy me much more than a Shimano 105 equiped carbon forked aluminum road bike today.
The other thing is with all of these bikes comes more bikes tools!!! N+1 can be applied to tools just as well as bikes. My bike tool collection started off with buying a used Park repair stand and some tools from a bike shop that was closing. It has now ballooned into multiple repair stands, truing stand, peg board and tool box full of various bike tools, and I am often adding more. I just ordered another tool this week from the LBS that I don't have and needed to take out a BB. Along with the more bikes and bike tools comes more parts and with that you need places to store parts. The bike hooks, S hooks and pipes, file cabinets, plastic storage bins, and other stuff I buy to hold and organize my parts is adding up quickly too. My next project is to wire in some more lights into the shop area.

P.S. Guitar collection is only at 3. I know I can't afford a vintage guitar collection.
